Extech EX900 ExStik 4-In-1 pH/Chlorine/ORP/Temp Kit

Surface Measurements of Chlorine, pH, or ORP Using a Flat Surface Electrode

• 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
• Large 3-1/2 digit (2000 count) Digital display with bargraph (pH bargraph originates at neutral point 7.00pH)
• 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
• Waterproof design floats in wet environment (IP67)
• 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
