Combo Testers are Excellent for Routine pH, Conductivity, TDS and Temperature Measurements
Rugged, floating Waterproof Combo Testers allow you to accurately measure the pH, conductivity, TDS or temperature of a solution without switching meters. Perform a self-check at start-up, then display battery level. Testers have automatic temperature compensation, autocalibration, a stability indicator and a hold feature to ensure proper measurement and to freeze the display for accurate recording. pH electrode, four 1.5V batteries and an electrode replacement tool are included. Choose from Low-Range (No. 89306) and High-Range (No. 89307) Combo Testers.
