Steps
1. Turn on the instrument power supply;
2. PH calibrating: use three-point calibrating at 25 ° C (4.01, 6.86, 9.18);
3. Electrode immersion in the solution to be tested;
4. Read and record pH value and temperature data.
Notice
• Permissible Ambient Temperature Range 0-50 ℃ (32-122F);
• Use 1.5V battery (LR44) * 4PCS as power supply;
Make sure the temperature is 25 ° C on time.
• Avoid use in environments beyond the specified Temperature range.
