Extech Model EX800 & EX900 Features:
- Model EX900: 4-in-1 Water Quality Meter measures Chlorine, pH, ORP plus Temperature with interchangeable flat surface electrodes (included)
- Model EX800: 3-in-1 Water Quality Meter measures Chlorine, pH 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; 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
