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

*To buy the calibration solution monthly is completely impossible!*

Now ”i see man” ;p

😂 I never claimed to be a professional pronouncer! Thanks for watching!

@@HydroHowTo Dont' worry you're not alone - just because we used to fix a particular Siemens product when on sites you would be brought to the toilets and shown a broken Siemens hand dryer or a broken Siemens Vaccum cleaner and were expected to know !

You’re welcome! I hope it was helpful!

You're so welcome!!! Thank you so much for subscribing and for the wonderful comments! If you have any questions once the meters arrive, please let me know 😁

@@HydroHowTo Thank you! 😊

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 ;)..

Good call, I talk about that in another video. Equally as useful here though. Thanks for watching!

Interesting. Will give this a try. Thanks!

can the original mixed powder solution be bottled up and saved?

Got this exact one for $9 on amazon 2 days ago.

Thanks for the awesome comment! If it helps you then it’s well worth my time and effort!

@@HydroHowTo 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.

You can order new buffer powders on Amazon. There should be a link in the description.

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.

You'll need the powder to make sure it's calibrated. You can buy just the powder on Amazon. I think there is a link in the description of this video. Thanks!

I don’t own an Apera 20.

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

Thanks for watching!

I don’t know that it’d help this meter.

You're welcome! I hope it helps!

Sounds like a bad meter

Just click again one or two times on the "CAL" button. Then it will flash and do the calibration. And wait for 30 seconds to let the value being set and then calibrate ph 4.00, then 9.18 and then 6.86. Repeat it several times until they show always (almost) the correct values.

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.

That’s beyond my expertise.

I found them on Amazon. I put a link to some similar ones in the description. Hope it helps!

I don’t know what you’re referring to.

@@HydroHowTo RU-vidr "Clean Food Living" and search "calibrate ph meter". You will find her method. It clears up the Chinglish that was used in the pH meter's instruction manual, in particular the "hold for 5 seconds" part.

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.

@@HydroHowTo thank you! That’s what I’ll get.

@@brittany16950 I think you'll be really happy with it!

I haven’t tried it, but honestly these cheaper meters are pretty hit and miss when it comes to quality.

@@HydroHowTo I guess I'll just have to calibrate and test it out myself. Thanks! Lol

True, but they don’t need to go 3 months without recal.

I've had mixed results with them. Some work great, and some are junk. I definitely think you'll be happier with a slightly more expensive, better constructed meter.

Drops are a good option if you have normal color vision. Yes, pH meters will fail, and drops will run out. Both are consumables. It all comes down to using what you prefer! Sounds like drops have worked out great for ya, and that's awesome!

Agree

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.
