2 x AAA batteries
1. Install batteries and power on the device.
2. Clean the probe with distilled water and wipe dry before measurement.
3. Immerse the probe front end into the solution without exceeding the water level line.
4. Read conductivity and temperature values on the display.
5. After measurement, clean the probe and cover it with the protective cap.
6. Calibrate the instrument if unused for a long time or after probe replacement.
Water quality testing for purity and contamination detection
