Overview
The QIWEI PHS-3C pH meter (Benchtop Precision) uses a white backlight to display the pH value or potential mV value at the same time. It is suitable for laboratory sampling in Universities & colleges, research institutes, environment monitoring, industrial and mining enterprises to determine the pH value and potential (mV) value of aqueous solutions.
Features
1. White backlight display, can display ph value or potential mV value at the same time
2. pH Measurement range 0~ 14pH, accuracy +/- 0.01pH
3.mV Measurement range 0~ +/- 1999mV, accuracy +/- 2mV
4. Measurement range 0~ 60 ℃
5. Resolution 0.01pH/1mV
6. Power Adapter or Power Cord
Principle
PHS-3C pH meter converts the activity of hydrogen ions in aqueous solution into electric energy by Sensor (pH composite Electrode), and the electric energy is input to the instrument. After operation amplifier and current detection, it is converted into digital display by A/D. The above electric energy conforms to the Nernst equation.
Applications
Universities & colleges, research institutes, environment monitoring, industrial and mining laboratories
Steps
1. Connect pH composite Electrode to Electrode socket (interface model: Q9)
2. Turn on the power switch
3. Use pH/mV switch to select measurement ph value or mV value
4. Use the positioning knob to adjust the value of pH6.86 standard buffer when calibrating
5. Use the slope knob to adjust the value of pH4.00 or pH9.18 standard buffer when calibrating
6. Use the temperature knob to set the temperature value of the solution to be tested
Notice
• Operating Environment relative humidity ≤ 80%
• Ambient Temperature 5~ 40 ℃
• The temperature of the tested solution is 5~ 60 ° C
• Power supply 220V/50Hz
Do not be disturbed by large vibrations and strong electromagnetic fields
