Overview
The LEICI PHS-3E precision pH meter is a Benchtop digital pH meter with a measurement resolution of 0.01pH and a mV value resolution of 1mV. The instrument supports automatic temperature compensation, is equipped with E-201F or E-301F composite Electrode, and can Measuring temperature. As a laboratory pH meter, it is widely used in chemical industry, food, scientific research institutions and universities.
Features
1.High definition LCD display, key operation
2. Support automatic shutdown, power failure protection and factory reset
3. IP54 Protection Ratings
4. Standard triple compound pH Electrode, Electrode bracket, dust cover and calibrated buffer powder
5. Intelligent determination of endpoints, support equilibrated measurement and continuous Measurement mode
6. Support automatic/manual temperature compensation
7. Support 1-3 point pH Electrode Calibration
8. Automatically identify three standard buffer solutions of GB 4.00pH, 6.86pH, and 9.18pH, and support custom buffer solutions
9. Support Data storage (50 sets), access, delete
Principle
The pH meter detects the concentration of hydrogen ions in the solution by a composite Electrode, converts chemical signals into electrical signals, and is amplified by a high Impedance amplifier and processed by a microprocessor to display measurement results. Support automatic temperature compensation function to ensure the accuracy of measurement in different temperature environments.
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 bottom, and tighten the nut
2. Install the power supply and plug it into the socket.
3. After connecting the power supply, check whether it 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
● PHS-3E precision pH meter is a precision instrument with high input Impedance, keep the input drying clean when using, and insert Q9 short-circuit plug to prevent water vapor and dust when not in use
PHS-3E precision pH meter and its power supply should be well grounded
● Electrode introduction line should remain static during measurement
● When calibrating, do not mismatch the solution, otherwise it will cause measurement errors
