HANNA® Waterproof Combo Testers

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.
