Review on Enhanced FYD Backlight Precision Calibration for Optimal Accuracy by Jose Muenzen

After reading the recommendations for ATC PH (Automatic Temperature Compensation) meters in many gardens, I decided to give it a try. I've used paper strips and only one of my analog pH meters seems marginally accurate at best as it doesn't compensate for temperature affecting pH. The digital display is much easier to read than the strips and accuracy can be measured using the calibration powders provided. I tested it on paper strips in water containing both high and low pH supplements and am happy to report that it was accurate right out of the box. I'm considering buying another one and when I compared purchases this one had the best price per unit. I would recommend it.
