How does an Infrared Thermometer work? - A Galco TV Tech Tip | Galco
Вставка
- Опубліковано 13 бер 2018
- Infrared is a type of energy that is emitted from the surface of all objects and is part of the electromagnetic spectrum. This works in tandem with what is known as emissivity, or the measure of the efficiency in which a surface emits thermal energy.
The IR thermometer then works by focusing the light that is coming from the object in the form of infrared rays and tunneling that light into a detector, known as a thermopile. This thermopile turns the IR radiation into heat, which then gets converted into electricity, which is then measured and displayed on the screen of your thermometer. This whole process can be achieved in seconds, or even fraction of seconds depending on your thermometer.

Actual "IR camera" gathers and displays temperature
Laser is to let you see what it's pointing to
"It's a single pixel IR camera with a laser pointer taped to it" would be a better explanation.
Thanks Nill. Which one should, which one is the best or is it even worth it. Could I use this in a human body as well? Thanks Nill
So the laser pointer is just for guidance, i thought that something was reflected from the red dot. ...it is just a pointer?? omg, like that was a bad explanation. Thanks man.
It's not a camera
Thanks for the summary
I know brief is good but this is ultra brief!
IKR, #1 result on UA-cam, I was expecting more than just a paragraph. Maybe an experiment or a teardown, something beyond what I could have gotten from the first paragraph on Wikipedia.
Lol it really was
Why not metabrief while you're at it ?
My kid asked me how a microwave oven works. I told her, "You put the food in the oven, set the time, and press start." She thought I was an idiot.
They are dangerous machines. Should never have been invented. This is what’s causing cancer. The radiation reduces all the nutrients in the food. You’re basically eating radiation food.
@@thewideawakeclub4843 Microwave radiation is a form of non-ionizing radiation. Non-ionizing radiation does not have enough energy to knock electrons out of atoms. So they can't alter atoms and molecules and cause damage to cells in organic matter. Food cooked in a microwave oven is as safe, and has the same nutrient value, as food cooked in a conventional oven. The is cosmic microwave background radiation all around us and has been for all our lives.
@@Seafury2004 its because the food is irradiated and not radioactive right?
Lmao
Anyone here after COVID 19 outbreak??
Me
It's not suppose to be pointed at you
@@zthreetwo9874 lol
Yes to see if they are slowly but steadily creating us a nice new tumor or cancer. Apparently not.
But she's hot
MONERISplayz ua-cam.com/video/awADEuv5vWY/v-deo.html it is invasive for sure
I just got one at Costco for $9 and I've been using it on practically everything... So i decide to look into how they work. Thanks for the video...
Do those things burn some body skin or toggle on your skin .and can you point it at some one that doesn't realize your useing it ok them.
?
@@mauricearcher8831 it only measures IR radiation so won't do anything to what it's measuring
How far can it measure?
I found mine in the marina skip the price was my favorite £0.00
The laser is only for aim XD
🙏😂 saved me some time
Oh, so the laser is simply an aiming device?
Yes that is correct.
That's the gotchya moment I just had as well.
No it's really a laser pistol uses to kill Storm Troopers.
I just realized the same thing
You don't REALLY answer the question in any substantive way.
I have a Hold feature and what is it for? Lost my manual.
Very valuable
What is the E= for? You can adjust it and I just don't understand
My friend thinks he takes temp of the clouds .. Whats your thoughts
Brief video is good but you have crossed the limit of brief...
At least explain something.
Her voice gives me anxiety like news anchors voices.
Vlad Pierre while a pandemic
Thankyou
Super👌👌👌👌👌

How is IR radiation converted into thermal energy? Could you please explain it to me?
Vsauce explained it very well in his Video, "How Hot Can It Get"
good
No one ever mentions what the laser actually does. Is it merely to make it easier to point the detector? If so that seems easy enough to say so why does no one ever SAY THAT?
you explain exactly how my professor does.
Your professor is a bimbo
Does it work to measure temperature in oil tank?
Do not use electronic devices other than those specifically designed for use with the unit, which will probably be a built in sensor or manual grounded gauge, idk. You were joking, right?
Watching coz of Ncov?
How far does it go? I shot mine into the sky. It says 7° F. It was 65° outside.
IR meters do not measure air temp, they need a reflective surface to see the temp. Different materials have different emissivity ratings. Check the manual for your meters ratings.
GalcoTV distance is 0-20 cm. Emissivity: 0.95 (fixed)
So there ya go, 20cm is less than 8 inches of distance. The emissivity of 0.95 means reflective but not necessarily polished either. IR meters are meant to measure surface temperature of objects. So if you want to know the outside temp with your IR meter then pick an object sitting in the shade and see what it says.
This comment made me laugh, shine it at the sun and see how hot it is
@@GalcoIndustrialso what is the difference with the ear thermometer that should touch the ear and forehead to take the measure? Is it have a different sensor?
head will burst if i hear her voice 10min.
I guess that's why this video is less than 2 minutes. I bet her summary of quantum physics would be the same length.
The laser is simply a led right? can you use it to measure the computer's motherboard temperature while its on? I suppose it won't short-circuit anything?
Yes you can use it on electronics. It will not cause a short. The laser is very low power and is only intended for pointing at a surface to measure.
@@GalcoIndustrial thank you

Who found this video because of the Pixel 8 Pro 😂 I also learned it can use to find air temperature too
Will these work to measure my skin temperature? Can it detect to 0.1 degree farenheit?
No it cannot measure your skin temperature accurately. At best its accuracy could be +/- 5F
CAN the temperature be taken in the ARMM instead of the head ????
IT SHOULD NEVER BE USED ON THE HEAD. THE GOVERNMENT ARE A BUNCH OF SATANIC LIARS. THEY’RE THE ONES WHO STARTED THIS. THEY GAVE US MISINFORMATION. BECAUSE THE SHEEP TRUST THE GOVERNMENT. THEY THINK THE GOVERNMENT CARE ABOUT US. WRONG. THEY ARE KILLING US.
Does the lazer do the reading or is it just to guide where you are pointing At and the actual device is driven by an invisible force?
The Laser is just for aiming it. The lens has an infrared sensor behind it to measure what ever is in front of it.
The laser is for aiming. And yes It is strong with Force.
Sorry I've been watching star wars
@@asandax6 , lol no problem. we have starwars fans here too
If you can see the laser pointer, it is in the higher frequency visible range that is not even detected by the meter. It just marks the center of a circular area whose IR (heat only) energy is detected. The diameter of the circle may be about 1/10 the distance to target. The more heat detected, the higher the temperature reported. If some of the heat detected is reflected from the target (i.e. target emissivity is less than 1.0 for heat) from something hotter or colder near the target, the reported temperature will be a weighted average of the two heat energy sources' temperatures. Taking the temperature of a mirror is likely to show the average temperature of the room walls and contents behind the meter reflected from the mirror, rather than the mirror glass temperature.
how close it should be directed at a person and any side effects using on humans?
The laser is just for aiming, it doesn't do anything else.
It's just a simple detector with a lens measuring the IR light that humans emit.
You can cover the laser if you want, but you will have a hard time knowing if you're pointing it at the right direction.
How come my laser infrared thermometer only reads 90-92 degrees on my & kids'' foreheads? Shouldn't it be 96.8 or near that #?
Because the skin surface has heat losses, The outside surface of the body will be cooler than internal.
NEVER USE IT ON THE HEAD!! EVER!!! WHOEVER DID THIS WANTS OUR KIDS TO DIE. THE GOVERNMENT DID THIS DELIBERATELY. JUST LIKE THE HAND SANITISERS. THEY ARE DEADLY CHEMICALS. THAT BEAM GOES INTO THE BRAIN INTO THE PINEAL GLAND. WELL DONE ON TRUSTING YOUR GOVERNMENT. COVID IS A LIE. SO WAS 9/11 SO WAS THE MOON LANDINGS.
My main concern here is accuracy. 0.5°C or less can mean the difference between normal and fever. Will adjusting the deviation account for the entire range of measurable temps?
Doctors in the far east say we should be pointing them at the wrists and not the foreheads.
I can tell you one thing for sure. The laser has nothing to do with it.
My country's "news" articles say this thermometer actually plants chips in your brain. Crazy, right?
@Dopey Dope Romania.
@Dopey Dope Ok, cyborg friend.
Of course, that's the only way they can track Daywalker Vampires..
@@jechega1867 It's Romania: Become Human here mate. Cyber-vampires.
does it use laser forBEAM TO MEASURE TEMPERATURE?
Raye
Wow... seriously I didn't get a thing of it
For corona?
mine is green light
This instrument has lead us into the greatest misunderstanding in science, greenhouse theory. Tyndall used it to define the greenhouse gases in 1859. The instrument poses a contradiction; all matter radiates - as correctly stated - but by this instrument not all matter does. The reason is that - I have deduced - not all matter is thermo-electric. More specifically, not all molecules have electric dipole moments that 'send' an IR signal able to be received (transduced into an emf) by the said thermopile. Nitrogen (N2) and oxygen (O2) are the perfect examples of this; they are not measured at any temperature by the thermopile, yet, they have a temperature. They are both very poor thermal conductors (0.026 no units) so they must radiate. From this instrument, we believe that the only matter that radiates - and the extent to which it radiates - is only determined by this thermopile. It defines the greenhouse gases. Emissivity is really and only a correction factor. Yet there is another complementary instrument that measures the IR that the thermopile cannot detect, The Raman spectrometer. Read my work at 'Quantum Mechanics and Raman Spectroscopy Refute Greenhouse Theory' vixra.org/abs/1811.0498 and while you are at it read 'The Greenhouse Gases and Infrared Radiation Misconceived by Thermoelectric Transducers' vixra.org/abs/1811.0499
In time I will overturn current radiation theory and make it coherent.
Ur gay
In time you will do jack shit. Spend your theorizing time connecting with friends and family.
@@EvanGisamazinglmao why so angry at a guy with a theory. Let the nerds put pen to paper and continue the battle of greater understanding every day.
The laser is for annoying people on the street or playing with your cat.
You can send me…?...
Yup, I still don't understand it. Lol
lol me neither
You both are Noobs I tell 😂😂
The laser temperature can be misleading. First off the government have been demonstrating this all wrong. By shooting this laser onto children’s forehead. This is very dangerous to the brain. The sheep trust the government. Even though they lied about 9/11 and the moon landings. Lied about Covid. They lied about hand sterilisers. They are full of deadly ingredients.
The thermometer picks up the surface temperature. So if the sun is shining on a child’s forehead it will read higher than the child’s actual body temperature. Which is misleading because then the dumb teachers will think the child has a fever.
It is also dangerous for the brain. The correct way to check the temperature is on the wrist.
Katie
she tries to seem very convincing while reading from that prompt
Why do I use this for my cat-?
For animal fever just look at their gums. Prolonged white = sick. Blue = cold. Red = potentially overheating (open mouth breathing is a positive for overheating). And the ears and feet pads, feel for excessively hot or cold.
People who searched this 👇🏻
Wow, I learned absolutely nothing...
Why do we point it at our foreheads
i thought they just made this for covid
IR thermometers have actually been around for a LONG time, but only recently started becoming mainstream.
humm, so it won't work in the dark?
It still works in the dark just fine, but you may have trouble aiming it if you can't see what your trying to measure
The illustration we use with what appears to be Sun light shining on the object is merely warming it to measure something. All objects emit this infrared signal that is always proportional to its temperature.
Change your tutor
Why?
That was the hottest explanation I've seen yet *cymbal crash*
Thank you, I'll be here all week please don't forget to tip your waitress...
Are you married?
Yes
Fuck off loser
Sorry buddy but as they always say there are plenty of fish in the sea.
which is great because you can get sea food on your date 🙄.
🤣🤣🤣
Awe, thats sweet!
pls be vegan animals also have lifes Radhe Radhe
i do not like any of these guns especially pointing at my forehead it just doesn't feel right.
I’m sure you think microwaves are dangerous too.
@@nicholasbeaufrand4752 well actually a microwave doesn't probe you and invasion of your privacy however, if you put a fly in a microwave and turn it on he will just fly around in there and when you open the door he will fly out , no problem.
Paul Culwell well this thermometer doesn’t probe you either. It receives infrared light from an object and converts it to temperature. The laser is just there to aim at whatever you want to measure. And it’s a low intensity laser. Won’t hurt you.
Flies have little to no water in them so the microwaves pass right through them. Any animal with a tad of h2o in its body would die a painful death.
subliminal messages
@@nicholasbeaufrand4752 I do.( microwaves) I have concerns about this thing being pointed at the third eye. Someone told me it’ll affect the pineal gland
