Review: Very satified - This was very easy to calibrate, and I was able to see my other PH device was off as I thought. I would suggest this to anyone especially since it is ac/dc.

### ⭐⭐⭐⭐⭐ Best monitor for the price

I’ve had this for about 2 years and still works like it’s brand new. Temperature is on point and very accurate with the pH. Battery life is great and this product is very durable. I highly recommend!

### ⭐⭐⭐⭐⭐ Very satified
*by S***R on December 29, 2025*

This was very easy to calibrate, and I was able to see my other PH device was off as I thought. I would suggest this to anyone especially since it is ac/dc.

### ⭐ No protective cap on probe, and it stopped working within days!
*by J***S on May 30, 2025*

This In tank Ph meter. Didn't read the temperature properly from the first day. It was 2.5 degrees off. I wasn't that concerned. But by the following week the Ph reading started flashing and would go up and up. I have a handheld Ph meter so I tested my tank to make sure it was OK. It was fine but this machine kept reading it way off. I turned it off and the next day it wouldn't give any reading for Ph, the temp was still working but wrong. So needless to say I took it out and returned it. Lucky I bought a different one for my other tank and it works perfectly so I bought a second one of those. As someone mentioned in their review when I opened this box the probe didn't have its protective cap on. They should always be capped and have in solution it. So if you order this and when you Open it, it doesn't have it's protective cap on the probe I would just send it back.
