Steps
1. PH calibrating: use three-point calibrating at 25 ° C, calibrating points are 4.0, 6.9, 9.2; 2. Measurement of the pH value or Electrode potential of the solution.
Notice
- Permissible Ambient Temperature Range 0-50 ° C (32-122F); - Use 1.5V battery (LR44) * 4PCS as power supply; - Ensure that the temperature is 25 ° C on time.
