  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)
• 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
