Digital PH Meter, PH Meter 0.01 PH High Accuracy Water Quality Tester with 0-14 PH Measurement Range for Household Drinking, Pool and Aquarium Water PH Tester Design with ATC

Perfect for my purposes of checking ph levels of water. It’s easy to calibrate since it came with everything you need to do so and took all of two minutes to accomplish. I use canned air to dry off the distilled water used to clean the probe between tests. Can’t beat it for the money.

Very easy to use AFTER being calibrated. You’ll have to calibrate yourself and to save the calibration water for future if needed to re-calibrate. I didn’t have to ever re-calibrate after first use but it seems to be pretty accurate to me. Works great for my plants and testing the ph level of the water needed! Very affordable too compared to the old methods.

Easy and simple to use so I can get my water to around 6 - 6.5 ph. Also , I use white vinegar to calibrate it if ever needed. White vengar ph is 2.4 . Hope this helps !

Though I would save a few bucks and try this Meter. Turns out I just wasted a few bucks. Not sure how this meter got so many positive reviews. It is not accurate at all. The reading vary +-2, which makes it useless. I bought a bottle 7.0 control solution to test it. Calibrated the meter using the powder that came with it, and the first test with the control solution came up at 7.0. Turned off/on the meter and the solution tested 6.1. Turned it off/on again and the solution tested 7.8. Re calibrated and tried again and same results.Bought the Apera AI209 Value Series meter for $45 and it is dead on every time.

A piece of junk. Gives inaccurate values after only 5 months. No warranty information on the seller's website. No recourse. Don't waste your money. Go buy a real meter.EDIT: So I found out that you need to store these things wet, in a KCl salt solution. The manufacturer did not say this. I stored in plain tap water for a few days and the meter started working again. Apparently the electrode dries out and stops working. Better instructions would have been nice.

Arrived fairly quickly. Decent instructions. If calibrated and used as directed it seems to function just fine.

Excellent!! It does exactly what is described by the seller. I highly recommend!

I used this to test the pH balance of home made Kombucha. It seemed somewhat off on the reading levels, but then it really became a problem when it did not work anymore just a week or two ago. Of course, I am just outside the window of return now.
