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.

You can get the kit for under half the price from ebay. Same pens without the expensive vivosun sticker for future ref :). Same as the digital temp meters that many company's and hydro shops sell for around $20 are only $3.50 - $5.50 in unbranded package ready for you to add a few of your own stickers and 100%+ price jump ;)..

You'll still want to be able to control the pH and EC of your solution, so I'd recommend some method of testing for sure.

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

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.

testing both meters at the same time might also factor in, since the meters are like voltmeters and they might be interfering with one another

Not with these cheaper ones. Normally with a nicer tool, like the Apera PC60, you would keep a drop or two of storage solution in the probe cap.

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...

There are MUCH better meters that will calibrate faster, more accurately, and will hold a calibration much longer if properly taken care of. These Vivosun (and all the cheap similar clones) meters are so so if you can get them to calibrate. Personally, I've been using the Apera PC60 for about 2 years, and I love it. You can check it out here: amzn.to/3WCSqf4 (affiliate link). It's a much higher price point, but it's an incredible meter.

Why not use say Coke to lower pH? Baking soda to raise it? Vinegar to lower. It's not the space program people. No need to buy pH up and down $$$$. Simple stuff you already have at home.

So is your Buffer solution bad? I don’t understand how a buffer solution with an EXACT ph doesn’t measure “6.86” ? Maybe there’s something idk 😂

I stopped using pH meters because they seem to get off. Just use the drops. No need to know the pH down to the 10th of a pH. Use the drop and make sure it is dandelion yellow. Everything will be great. Save your plants, save your time, save your money. pH meters are junk as they all ways fail given time.

But that doesn’t work so well if color blind and everyone has a different idea of what different colors are. I have a friend who views an orchid of mine as purple, I couldn’t figure what she was talking about which picture -- it turns out it was a pink. So I thought maybe it was me. Went to the description from various vendors on their description (this is a mericlone) and it was pink. But she saw purple, light purple. If it was over the internet, it could have been the setting of her screen. But not in person. So deciding from a color is not a great idea. Same with using test strips - you are matching colors.. maybe a little better but can have the same issues. And also I was always taught to not turn a wet meter upside down. And in fact, my last meter which would have been a more modern one, had the information in the manual. But there this guy is turning his upside down pretty as you please. They also tell you not to get above the insertion line for the same reason -- why.. because you don’t want any water to seep back up into the electronics. The same thing happens when you turn it upside down.

Also reading numbers in a digital piece of equipment is always better. Always use fresh distilled water, never opened before to make up calibration solutions. When it’s been opened, it can pick up carbon dioxide from the air quite fast even over 48 hours. Dramatically so if just left sitting open to the air. I like to take my 1/2 gallon bottles when opened and place in glass quart or pint jars. Or if you can find, buy in quart/1 Liter bottles. I never see them And make sure you don’t accidentally use spring water.
