Extech EX900 ExStik 4-In-1 Kit

ExStik 4-in-1 Kit - Chlorine, pH, ORP, Temperature The Extech EX900 ExStik 4-In-1 Kit includes the CL200 meter, pH and ORP electrodes, reagent tablets (50 tests), four plastic cups, a weighted stand, pH buffer pouches, four CR2032 batteries, 48-inch neckstrap, carrying case, and user manual. The meter measures total chlorine, pH, ORP, and temperature with interchangeable flat surface electrodes that are included. Features Overview Flat surface electrodes work in liquids, semi-solids and solids. Built-in memory can store/recall up to 15 readings and save the last calibrated value. It has a large 3-1/2 digit (2000 count) digital display with a bargraph and an automatic electronic self-calibration function for chlorine and ORP (1, 2, or 3 point buffer calibration for pH). Additional Functions A smart chip predicts pH electrode performance with RENEW indicator when replacement is needed. A CAL indicator alerts user to recalibrate pH electrode. Additional features include: automatic temperature compensation, data hold, auto shut-off and low battery indication. This meter can simultaneously display ppm or pH and temperature (degrees C or F).
