VIVOSUN Aerolab Digital pH Meter Kit ±0.01 High Accuracy, Waterproof pH Tester Pen with Replaceable Probe, LCD Display, Auto Temperature Compensation, Calibration Powder for Hydroponics, Gardening

Ph tester not much I can say its digital display, works as intended

Works well, how accurate not too sure but it's done what I needed.

I am not too confident in this, it’s very easy to use. The accuracy of the tds I think is good, the thermometer takes a while to get to where it needs. It’s cheap and easy to read. Appears to be waterproof as well which is kind of essential but you never can tell the durability on some of the cheaper products.

Worked fine for about 6 weeks and then the digital panel started to act up. Last week I could barely see the results, now it is all gone. Leave this one, buy one with a brand name.

Even straight after calibrating this was about 5 points off no matter how many times i recalibrated and within a month of use it just started throwing up random numbers,I did keep it in storage solution and used a PH meter cleaner,It was giving readings like 9.0 for distilled water.More landfill crap

I bought an older version from vivo sun and was ready measured, this one need to do it with the powder solution

The pH meter seemed fine at first, followed the instuctions to calibrate but it didn't work.

This is my 2nd buy of this model My first one still worked great but I gave it to a friend and bought another I love gardening and my annual flowers The fertilizer I use is excellent and i use the EC meter option for this Excellent meter
