Extech EX-900 EXSTIK 4 IN 1 KIT (CL, PH, ORP, TEMP)

Automatic electronic self calibration for Chlorine and ORP; 1, 2 or 3 point buffer calibration for pH. Data Hold, Auto shut-off and low battery indication. Easy to replace electrode modules. Waterproof design floats in wet environment. Direct reading of Total Chlorine from low detection limit; Unaffected by sample color or turbidity. Simultaneous display of ppm or pH and °C/ °F Temperature. Smart chip predicts pH electrode performance with "RENEW" indicator when replacement is needed. "CAL" indicator alerts user to recalibrate pH electrode. Automatic Temperature Compensation.

4-in-1 Water Quality Meter measures Chlorine, pH, ORP plus Temperature with interchangeable flat surface electrodes (included) Flat surface electrodes work in liquids, semi-solids and solids Memory stores and recalls 15 readings and saves last calibrated value Data validation indicators show user the reading is stabilized Large 3-1/2 digit (2000 count) Digital display with bar graph (pH bar graph originates at neutral point 7.00pH)
