### ⭐⭐⭐⭐⭐ Worked just fine

Worked just fine

### ⭐⭐⭐⭐⭐ Five Stars
*by M***K on May 17, 2017*

Great price fixed the meter back to right.

### ⭐ The pH probe will not calibrate
*by C***S on June 20, 2025*

it calibrated easily and worked great for 2 months, then mysteriously malfunctioned. I check the ORP storage solution religiously every week to make sure it's fresh and new, and still the pH will not calibrate (3-point) - it just floats in values and over 1 to 2 full pH units over each calibration solution (4, 7, and 10).
