The Hach Pocket Pro+ Testers are engineered to deliver accurate results. Backed up with built in performance diagnostics, you never have to guess when to clean or calibrate the sensor. You also get replaceable batteries for field use, and a large, easy-to-read LCD screen.
Easy calibration steps and built-in diagnostics for pH testers take the guesswork out of calibrating the sensor to keep it in optimum condition. Easy-to-replace AAA batteries and a convenient sample cup make maintenance and measurements simple.
