Turn them all on se what happens ?

🇺🇲🤝🏻🇯🇵

😮😮😮😮😮😮😁😁😁😁

It doesn't detect cigarette smoke, but particles regardless of if they're from cigarettes or from some other source!

why does it get out of range if your tvoc is 53 ppm and measurement range is 100 ppm?

Can I use this in an apartment I rent out?

Can I use this in an apartment I rent out?

what is the minimum detectable level is it lower then the smell?

The casinos in Las Vegas the filters are amazing!

👍

Can you install this in a HVAC system, like in a vent, etc...

Can you tell me how can we buy it

Why does the oxygen sensor degrade faster than those for other gases? It would be because when purging (rinsing) with atmospheric air, it contains oxygen, but not the other gases. In summary: does the presence of oxygen for long periods of time make the oxygen sensor degrade faster? Thanks for the excellent videos.

Bs

I need one !

what is the maximum pressure and lpm you can measure and put it through, like whta would happen if you try to go above 10 lpm to like 12 lpm for instance?

Its carbon monoxide

"as you could see" i couldnt it was out of frame the whole video

The camera movement makes me feel like I'm in a room full of carbon dioxide

By the way, what is a "BUMP"test? Robert Landfield

Thank You, I finally received your FD-91 RED Gas Leak Detector (Natural Gas/Methane). Dr. Koz's "Welcome" says "PDF user manuals are our website". Which website? I haven't been able to find them. Be kind, and make it simple for me, I will be 95 Fri, 8/30/24. Bob Landfield

I use something like this every day to avoid breathing second hand vape (for 2 years). Vape is a very bad form of air pollution and an irritant to a lot of people including myself. I use it mainly on public transport which is badly policed with regard to vaping as it is too easy to conceal. I have no problem with cigarette smoke, but one person vaping produces the same ultra-fine particles of 3,800 people smoking and it's those that cause the problems for me. Your exposure to vape is relative to the level and how long you breath it and it's very difficult to tell straight away if it's just at the level of 'smell' or 'exposure'. Ultrafine particles lodge deep in the chest and go straight into your bloodstream and every organ of your body. The only way I can stop it being a really bad problem for myself is to rinse my lungs and nasal passage in the shower every night. Smoking is way bad for the people doing it to themselves, but vaping is worse for everyone else.

Ok !

How can we buy

Bough one last week due to sewer gas odor in garage pipes. Followed the directions & tried all settings. Not once did it register any reading & the odor was obvious. Disappointed & sent it back.

Is he on coke? He's moving about like a thunderbird and shaking his hand like adolf

Does this detect only acidic vapors or gasses too? I'm asking this because acidic gasses can exist in both forms - as vapors in the moisture or as gasses. HCl for example can dissolve in the moisture in the air easily but in the case of low humidity, it remains in the gas form. Does the humidity need to be high for accurate measurement? Let's say we're in a relatively low humidity (40%) and there are high amounts SO2 and NO2 in the air, will this monitor measure the levels accurately?

What's the lifespan of this product?

oh if your PM2.5 and PM10 are 3 and 3 then you are in a very clean environment, indeed if PM2.5 is the same as PM10 it means that it is null, so you better try to NIST calibration! :-)

Will it detect cresote gas

That's exactly why i stopped dry herb vaping Same results

Sir i have a doubt can i have your insta id please

that is diode type TVOC detector od PID?

why does it indicate motor test at start if specified as diffusion?

how do you calibrate particle counter and is it NIST calibrated?

I have a question regarding a gas odor from A/C which type of gas is it ?

Does this meter go up to 1000 ppm?

is it possible to detect ozone in water, please? Thank you very much.

Until kids keep putting tape over the Lazer over and over, setting off the alarm enough until admin gives up on it.

Hi , id like to know if this equipment has pc connection in order to se the data that results in the prove

what is the difference between this and NIST calibration?

does the sensor replacement effect the warranty and NIST calibration?

this is in China?

Omg... 2 minutes in and I'm so annoyed. Get on with it How do I use it!?

"best selling" is only an indicator of marketing skills.

Why has no-one posted a comment? This is a fantastic product!!!

I dont think homes in the US have the home hvac in the garage as well. Not normally anyways, some people may add it in.

I can’t find a charger cord anywhere, can you help me out please? Thanks a million for any assistance you can provide.

if replaced does it have to be from the same manufacturer and what is the difference by brand?

could it be replaced semiconductor sensor for TVOC by PID?
