Principle
The pH meter detects the concentration of hydrogen ions in the solution by a composite Electrode, converts the chemical signal into an electrical signal, and displays the pH value or mV value after being processed by a high Impedance input circuit.
Applications
Chemical industry, food, scientific research institutions, colleges and universities
Standards
GB 4.00pH、6.86pH、9.18pH
Steps
1. Unplug the Electrode base bracket, unscrew the lower nut of the Electrode bracket, install the Electrode bracket to the base and tighten the nut
2. Install the power supply and plug it into the socket.
3. After connecting the power supply, the inspection shows 0mV (no more than 0 +/- 0.2mV).
4. Install the Electrode on the Electrode bracket, unplug the short circuit plug, and connect the PH Electrode.
Notice
• Keep the input dry and clean, and insert the Q9 short-circuit plug when not in use to prevent water vapor and dust
• Instruments and power supplies need to be well grounded
• Electrode lead-in remains stationary during measurement
• The solution cannot be mismatched during calibration
