How to Calibrate a Vivosun pH Meter + Vivosun pH Meter Review

This Vivosun pH Meter kit includes a pH & TDS/EC meter for around $20. In this video, I'll show you how to calibrate the pH meter, and then I'll test both meters for accuracy.

For the price, the Vivosun pH & EC meter kit offers a lot of value. The pH meter is easy to calibrate, and the EC meter is accurate at lower strengths right out of the box.

If you use the pH meter regularly, make sure to recalibrate it to keep it accurate. I recommend buying additional buffer powders so you don't get stuck in the middle of a grow with an inaccurate pH meter.

I am a retired chemist. Thank you for your video. Unfortunately, most people don't calibrate their meters and could be relying on inaccurate reading.
My only comment is that pH meters should be calibrated before each use. We calibrated highly accurate and precise (and quite expensive $1, 000) meters and probes AT LEAST DAILY. So, I would suggest for inexpensive meters calibration be performed before use on a a particular day. Obviously, if you are not using it on a particular day, there is no need to calibrate. The calibration solutions can be stored for at least a month if you always rinse the meter before dipping into those solutions.

Also, just a note that the pronunciation of SIEMENS is "See-mens", not sy-mens.

Having worked for Siemens AG Munich it's the first time I've heard Siemens pronounced that way ! Thanks for the pH information

Thank you! I lost my instructions on this and I was clueless. I kind of got rushed into this all last second, and I’m feeling my way through it. Lol

Thanks. I would also record your findings in a journal for reference and check findings over time with each system in use to figure what works or went wrong and what you did to fix the problem.

Just what I needed! I ordered this last night and it should arrive tomorrow. Thank you. Subscriber 501! Great info you got so far.

For the problem with wrong calibration values... 👇
Just click again one or two times on the "CAL" button after pressing it for 3-5 seconds. After choosing the one you need it will flash and do the calibration process.
And always wait for 30 seconds to let the value being set in the solutions and then calibrate in this order: pH 4.00, then pH 9.18 and then pH 6.86.
Repeat it several times until they show always (almost) the correct values in the solutions...

awesome just what i was looken for EC meter and how to read since we dont have decimals on the reader just needed to be positive thannks

When you have a calibrated meter you can prepare your own test liquids using PH Down and keep them bottled up. Then there is no need at all to purchase anymore of these crystal test sachets.

Thanks man, I appreciate your time and effort!

[tacticaldragon]

well id say yes you right but i also say you need the meters at the same level in the water and no tmoving up or down while you are checking it, that goes for both meters sticks.

[justiceall]

I have the meter however I don't have the packages of powder. Will it still work?

[richardappiah_kubi]

I have lost the calibration powder. Are there any alternative means to recalibrate my pH meter?. Kindly help.

[nonenone]

Do you do anything special to protect the probe?

[etchd]

When trying to calibrate as the instructions say it tries to do 4.0 no matter what

[laurabarbato]

Do I want to do this for the wicking tote technique of your other videos?

[sugargraham]

Can you please tell me how to do a factory reset on the apera 20 😢😢😢

[kenmandu]

Is this video correct, or the "Clean Food Living" video correct? It would be great to have it clarified.

[bartseller]

Where do you get those little measuring cups?

[guttagutta]

$20??? That’s wild. They’re now $12 for this kit.

What do you do when you try to calibrate it in 6.86 solution but it says it's in 9.18 and calibrates to that? I try to calibrate in 4.01 and it says it's in 6.86 and calibrates to that. How to reset it?
