Overview
QIWEI PHS-2C Benchtop Precision pH meter is a High Accuracy measuring instrument for sampling the pH value of aqueous solutions and the measurement of Electrode Potential (mV value). It is suitable for laboratories in industrial and mining enterprises, scientific research, agriculture, teaching, environmental protection and other units. The instrument has dual functions, standard E201-C composite Electrode, Measurement accuracy is +/- 0.02pH, optional rhombus bracket.
Features
1. High Accuracy measurement, pH Measurement accuracy is +/- 0.02pH
2. Dual function, can measure ph value and mV value
3. Standard E201-C Composite Electrode
4. Optional diamond bracket
5. Up to 0.01pH/1mV resolution
6. Measurement range: pH 0~ 14, mV 0~ +/- 1999mV
7. Measurement range 0~ 60 ℃
Principle
The instrument is connected to the pH composite Electrode through the Electrode socket, and the pH/mV switch is used to select the Measurement mode. When calibrating, adjust the value of pH6.86 standard buffer through the positioning knob, and adjust the value of pH4.00 or pH9.18 standard buffer through the slope knob. The temperature knob is used to set the temperature value of the solution to be tested to ensure the accuracy of measurement.
Applications
Industrial and mining enterprises, scientific research, agriculture, teaching, environmental protection
Steps
1. Connect the Power Adapter or power cord to the power outlet
2. Turn on the power switch
3. Connect pH Compound Electrode to Electrode Socket
4. Use pH/mV switch to select Measurement mode
5. Set the solution temperature according to the temperature knob when calibrating
6. Use the positioning knob to adjust the pH6.86 standard buffer value
7. Use the slope knob to adjust the pH4.00 or pH9.18 standard buffer value
8. Conduct sample measurements
Notice
• Operating Environment Temperature should be within 5~ 40 ℃
• relative humidity should not exceed 80%
• The temperature of the tested solution should be within the range of 5 to 60 ° C
• Power supply is 220V/50Hz
• Avoid use in a significantly vibrating environment
• Avoid strong electromagnetic field interference
• Make sure that the Electrode socket is firmly connected
