It is astonishing that after more than 2 years and nearly 40k views of this video, that the Vivosun website information for this unit still says; "TDS Meter: Include EC, TDS, and Temp Function, TDS don't need to calibrate." They are fully aware of this video as I was in contact with them in relation to this issue from the day mine arrived in the mail.
i always see videos were EC is expressed in a whole number usually single digits. am i missing a conversion for the huge numbers given by these meters? thx for the video
@@goochma The 0.5 referred to is the conversion factor these devices use to create the ppm display from the actual measurement of electrical conductivity. The meter doesn't actually measure the parts per million. When my meter was calibrated to the 1413 solution (1412 on the display) you multiply that figure by 0.5 and the result is 706, which is how it determines the reading for ppm. If you test a solution of 1000 uS/cm in EC mode, it will give a ppm display of 500. This is shown in my other video where I calibrate the device using plain salt.
You’re the best my man. Just ordered a few more of these for my setup since I am always misplacing them. The spread across the new ones that come “calibrated” I crazy! 200-300 ppm difference in the same liquid between different meters. So it’s January 1st 2024 and still same xrap from vivosun
Really the only person who really show how to calibrate the meter every single other video says it show how to calibrate this meter when all they showed was its a couple digits off so its good. Really man much love for this video.
They don’t know how because they have bought a thousand of the cheap Chinese pens and had their names placed on them. Shovels, machetes, motorcycles, pH or TDS meters. Buy them cheap, customize them, sell them high.
I have an apparently identical (unbranded) device and it is not able to discriminate among filtered water, tap water, and commercially produced 'purified' water. What's more it sucks up the sample into its internals only to pour our of the battery housing as you try to dry the electrode end. I was in contact with the vendor (on eBay) and it was obvious that they had no more knowledge than I did. It is useless without proper instructions. Well done for persisting with the thing anyway, thanks.
Hey mate I came across you in another video comment section reviewing this meter and explaining your on going saga with vivosun. Hope those muppets compensated you for doing their job for them. Either way on ya for posting a clear and concise video on how to calibrate this meter. Bloody legend. One question. Do you need a fairly sensitive set of scales to measure out the potassium chloride or can you use 1/4 teaspoon for example or similar unit of measurement? Cheers
Thanks Angus. Firstly, no, Vivosun stopped responding at the mention of money but I decided to publish the calibration method anyway. Second question, I used a small digital scale, accurate in grams to 3 decimal places. These are pretty cheap on Amazon. In my follow up video I show how to use table salt and teaspoon measure to calibrate to a value that is pretty close but not exact. It's what I explained to you in the comments on Jimmy's video channel. It will give you readings that are within a reasonable accuracy range for most purposes. Let me know how you go and feel free to ask any questions.
The manual of my EC meter(same device from appearence) tells, after adjusting the value with the up down buttons press and hold the shift button for 3 seconds. Don't know if this matters since the outcome seems to be the same. Never the less I noticed that calibration seems to shift the value but not stretches the range. Means, if you calibrate it to a 500 µS solution, the value for 1413 µS will be off. The same, the other way around. If you calibrate to 1413 µS, the 500 µS will be off (at least on my device). I try to find out if there's also an option for adjusting this "stretch of the range". I'd found a web site where a guy pulled off the display cover and found a set screw underneath, right next to the shift button. He sayed he was able to calibrate the device by this set screw. Seems he didn't knew about the "normal" calibration feature. But, maybe this set screw is worth a try too...
Always recommended to calibrate to a known solution as close as possible to the range you are expecting to measure. If I was measuring drinking water I'd calibrate to a known low ppm solution like mineral water. For aquarium use, a bit higher. For Hydroponics I use the 1413. I saw videos with the little hole under the display cover as well, and people drilling holes in the units etc, but didn't go down that path. It wasn't required once I worked out which buttons to push. Again, Vivosun didn't have a clue. Possibly still don't.
@@gdlivo3353 Yes, "calibrating as close to the range you expect to measure" that seem to be best practice. Luckily my TDS/EC meter came with a manual describing the calibration process just as you explained it here. This device seems to be sold by many different names and resellers. Apparently they don't all give a proper manual with it, but you figured it out anyway. For that very reason I thought, maybe there are even more calibration features. ;) By the way: All that devices have in common the name "TDS & EC meter (hold)" and appearance of the housing. If you google it, you may also find some more manuals, but I guess you figured that out already.
Hello! Do u know which scale the tds meters is calibrated? I have 2 others from another brand and they'r showing a little bit less. My water with nutrients saying its 2530ppm at vivosun meter and 2000~ppm in two differents equipment. sorry for my bad english. thank u!
The Vivosun meter it is using the 0.5 conversion factor scale. So 1000 ppm will read 2000 uS/cm. Regardless of which conversion factor it uses the ppm readings of all 3 of your meters should be quite close if they are all calibrated correctly.
When I turn on my vivosun TDS meter it shows 1000 as the starting default measurement on both ppm and us/cm options when it is not submerged in water. How can I reset the meter so 0 is the default reading?
I wouldn't have a clue. You probably can't and it doesn't matter anyway. The only thing that matters is that it is calibrated and gives the correct reading when it is in a solution. What is says in air is meaningless.
Hi Trying to work out your sums is it 373g into 500ml of water of the potassium chloride sorry to be so ignorant but i'm new to hydroponics and thank you for the video.
i have the same blue tds meter, but when I press cal button it always treat the water as 1000 mS. and up/down feature isn't available. the irony is it was working fine until I accidentally pressed this damn button. so now I ordered another one device.
@@gdlivo3353 I found them and only 4.5 USD each meter in a set so 9 USD. They are exactly like the Vivosun. While they do not show the up and down and cal it works precisely the same way as this (a hidden function). Not even with them do they show how to calibrate the EC meter. Potassium Chloride I really do not wish to purchase something else from Amazon right now so can sodium chloride be used instead? After calibration of the pH meter, with the three packets, I found it to be 0.2-0.3 off and the best was to just use the 6.86 packet to calibrate with. Add the 4.00 to the testing it was off by 0.2 but add the third packet to the testing it swung out even more. I wonder if the EC meter is just as much of a turd too?
@@gdlivo3353 On Monday UPS is coming to pick these up and Amazon will refund me as they are broke. I would purchase a more expensive pH meter but to have to replace it every 18 months, give or take, is just ludicrous. Something to do with the bulb and some have head replacements, but they are almost as expensive as an entirely new meter.
If you mean the HM Digital one, I think it has an adjustment screw at the top on the back. You just put it into a known solution and use a small jewellers screwdriver to set it. I'll check when I get home.
Hi Sir, My fish tank water shows up between 400 to 750 ppm. Do you think it is okay ? I have tried tap water (that everyone can drink straightaway) and it still show around 300 . I am in London so I believe water quality is good but dont know why it show 300 to 350.
Your fish tank will give a higher ppm reading than tap water because it contains nutrients from the fish waste and other things like plant matter and uneaten fish food. This nutrient is the principle of aquaponics. It is not a problem if the water is balanced and doesn't contain high levels of harmful elements.
That wouldn't really achieve anything. It is always best to calibrate to a solution close to what you intend to be testing. Plus, it is recommended to calibrate this meter to 1413.
1413 solution is meant to be 25'C. My solutions started at 25 but moved a little. It won't matter or make much difference with 1 degree either way. If your down to 20 or up to 30 it will make a difference. Temperature correction charts are probably available but it isn't a precision instrument anyway.
i have my 1413 solution and im stuck at the blinking screen because whenever i try to calibrate it just keeps switching back to the ppm mode, neither of the buttons are allowing me to adjust..
Not sure what's going on. You need to be fairly quick to start calibration once the Cal button causes blinking screen. What reading is the unit giving for the 1413 uS solution? You will notice in the video that I had the same thing happen on the first attempt.
@@gdlivo3353 initially it was 1600, i tried adjusting but it just sent the numbers to a high 800, since then i’ve been trying to put it back up and it has been giving me an issue since.
@@carlorueda9058 Try pressing the down button first once the screen is blinking, to see if you can adjust down and then go up. Otherwise, I'm not sure what the issue is.
You will never make accurate solutions using measuring spoons. You may get close to required concentrations if you know the amount your spoons hold. The problem is that measuring spoons are not standardised,
I dont know what I did with my meter but now shows a EC but to the right I have a x10 number how do I remove it please !! or how can I reset to factory settings ?
You haven't done anything wrong. That is how the EC meter tells you that it is reading over 1000. So it goes from 0 to 999, then 100 X10 (1000). If it says 102 X10 it is reading 1020 uS / cm etc. If you followed the video instructions to calibrate it, then it is giving you the correct reading and your solution has an Electrical Conductivity of over 1000 uS / cm. It is not a mobile phone that can be reset to Factory Settings. All you can do is re-calibrate using a known value calibration solution following my instructions as shown in the video.
@@chrisk5834 I would suggest that you have a faulty device and you need to proceed to the Warranty procedure through either Vivosun or Amazon. If your meter jumps from high 900's to low 100's X 10 then that is to be expected for solutions close to 1000. What you are describing would appear to be a faulty meter.
