Comments

Rose: I've only used the PH tester so far, and it is accurate enough to meet my needs (tested against my GH PH test kit). I did struggle getting the device to initially calibrate for some reason; instructions seemed simple enough, but I must have been doing something incorrectly.

Kindle Customer: This works well for my hydroponics and my pool. I didn't calibrate the pH meter at first because it seemed pretty accurate, it read 6.5 in 6.8 solution, close enough for my purpose. I did calibrate it later, and it was simple. I hope it continues to work well. I rinse it in distilled water and dry it after each use. The TDS meter works well too. I just wish the part you stick in the water was longer. Sometimes it's hard to see how far it's in the narrow mouth hydroponic mason jar.

Geo thee great: Arrived quickly but I didn’t use it immediately once i did it didn’t work at all...it was a cheap ph meter so I ordered another one...I had to calibrate it but it worked...two days later when I actually needed it it wasn’t workin again...too late to return original so I’m attempting to return this second one and jus ordered another one because I can’t find one locally...hopefully third time is a charm Rt 🤔

Tory T.Tory T.: Ordered a brand new one of these and it didn’t calibrate correctly so Amazon sent me a replacement. I received it in a box saying it was refurbished and guaranteed tested to work. Upon opening the box, I found this note from the old customer, as well as a calibration package missing. 0/2 on this item so far. Don’t waste your time or money on this product. Order an HM

Adam Drew Griser: Easy to use. Good price for a set of these meters. Both a PH and TDS meter was included for $17.99. The PH meter though could have included another set of calibration powders if I would need to calibrate it a 2nd time but could prob find a workaround for this by finding a water source with a known ~6.86 ph.
