🌡️ PrecisionPlus: Advanced Back Lit Digital Temperature Aid for Professionals Review

Product used as stated, not calibrated when delivered. I used the calibration powder according to the instructions, after numerous error messages I was finally able to install it on the sixth and fourth levels. but he never read them like that, he just wavered wildly. will spend more money for a good one.

Needed a replacement for my old pH meter, unfortunately this product never worked straight away. or not and for the cost of the product I see no point in bothering with returning it so I got the paperweight thanks

This pH meter is awkward to use because it has to be calibrated frequently. I gave 2 stars instead of 1 because it's not too expensive and it's good enough if you just need an approximate pH. The seller's description says it's a "super accurate and reliable gauge," but it's not. I have a dozen aquariums and I check the pH 3 or more times a week and also check the tap water used when adding fresh water to the tanks. When I received the meter it was off by 0.5 when testing the pH of lab grade…
