Overview
QIWEI PHS-3DWB pH meter is a Benchtop microcomputer acidity meter with integrated temperature Electrode, LCD display and touch button operation. The instrument supports automatic temperature compensation, automatic identification of calibrated solutions, Data storage and extraction functions, Measuring accuracy up to 0.01pH. Built-in battery, can support 10 to 15 hours of continuous operation on a single charge.
Features
1. LCD display and touch button Operating interface.
2. Integrated temperature Electrode, support automatic temperature compensation function.
3. Ability to automatically identify calibrated solutions.
4. Data storage and extraction functions.
5. Built-in rechargeable battery, long battery life.
6. Measuring accuracy is high, up to 0.01 pH.
Principle
The PHS-3DWB pH meter detects the concentration of hydrogen ions in the solution through its standard E201-C-L Glass PH Composite Electrode to measure the ph value. The instrument also uses Temperature Electrode to monitor the temperature of the solution, and corrects the pH Measured value through automatic or manual temperature compensation function to eliminate the influence of temperature changes on the measurement results and ensure the accuracy of the reading.
Applications
Food, chemical, environmental protection, education, and scientific research departments
Steps
1. Turn it on and check the status of the instrument.
2. Use pH buffer to calibrate the instrument (the instrument can automatically identify the calibrated solution).
3. Immerse the PH Composite Electrode and the Temperature Electrode into the solution to be tested.
4. After the instrument automatically performs temperature compensation and stabilizes, it reads the ph value displayed on the LCD screen.
5. Data storage is available after the measurement is completed.
6. Shut down or enter standby mode.
Notice
• Please make sure that the Ambient Temperature is used under the conditions of 0~ 40 ℃ and the relative humidity is less than 85%.
The standard temperature Electrode is only suitable for measurement of solution temperature in the range of 0-65 ° C.
• PH Composite Electrode is suitable for solution temperature measurement at 0-100 ° C.
• Temperature range of the instrument automatic temperature compensation solution is 5~ 60 ℃.
• Clean and store Electrode properly after use.
• Please use the original Power Adapter for charging.
