Overview
The YONGLIDA PHS-25C digital acidity meter is a digital pH meter that can quickly and directly display the pH value of liquid samples. The measurement acidity value is displayed through the LCD digital display screen. The instrument uses manual temperature compensation, can perform one or two point calibrating, provides power through AC, and the measurement pH range is 0.00~ 14.00pH. Measurement accuracy is +/- 0.05pH.
Features
1. Quickly and directly display the pH value of the liquid sample.
2. Adopt LCD digital display screen for intuitive reading.
3. With manual temperature compensation function.
4. Support one or two point calibrating.
5. Measurement range, 0.00~ 14.00pH.
6. With mV measurement function, the range is 0~ +/- 1400mV.
Principle
Electrode detects the concentration of hydrogen ions in a liquid sample and generates a corresponding potential difference (mV signal). The circuitry inside the instrument converts this potential difference signal into a ph value and displays it directly on the LCD screen. The user can manually set the temperature compensation to correct the effect of temperature on the measurement result.
Applications
Laboratory water quality testing, industrial production process control, environment monitoring, education and research, food and beverage industry, agricultural soil analysis
Steps
1. Connect the 220V AC power supply.
2. Immerse the Electrode in the liquid sample to be tested.
3. Perform one or two point calibrating as required.
4. Manually set or compensate for the current solution temperature.
5. Wait for the reading to stabilize and read the ph value from the LCD screen.
Notice
• Please make sure that the instrument is connected to the correct 220V AC power supply before use.
• Before measurement, it is recommended to calibrate as needed to ensure Measurement accuracy.
• Pay attention to manual temperature compensation settings.
• Electrode should be properly cleaned and stored after use.
Measurement accuracy of the instrument is +/- 0.05pH, please pay attention to the error range.
• Do not use the manual temperature compensation function outside the temperature Measurement range of 0~ 60 ° C.
