TASI TASI-670A PH acid alkalinity meter pH range: 0.00~14.00 Temperature range: 0 ℃~ 80 ℃ (32 ° F~ 176 ° F)

PH pH meterOverview of TASI-670A

TASI-670A PH pH meter is a PH pH meter with white shell and external PH electrode, which is used to test the pH value of various aqueous solutions, etc., and the LCD screen displays both PH value and temperature value, which can be manually or automatically compensated during the test process to prevent the temperature change of the analyte from affecting the structure of the test. Also, in terms of data management,TASI-670A PH pH meter has a data storage function, which can store the values of 128 groups of tests, which is convenient for subsequent data analysis and other work.TASI-670A PH pH meter has the characteristics of accurate and stable measurement, compact structure design, and simple operation.

pH measurement with a pH meter 

1.TASI-670A PH pH MeterCalibrate the pH electrode prior to measurement. 

2. Connect the pH electrode to the BNC socket. 

3. Use the slide switch to select pH_A or pH_M. 

4. According to the introduction of the product manual, different temperature compensation operations are carried out in ATC mode and MTC mode.

5. Put the electrode into the solution to be measured,TASI-670A PH pH MeterThe pH value is displayed. 

6. After the measurement, clean the electrode with distilled water. 

PH pH meter calibration steps

1. Select pH_A gear and °C (or °F);

2. Press the CAL key for about 2 seconds to enter the calibration program;

3. Put the pH electrode into the standard solution pH4.01 and stir the standard solution;

4. Wait for pH and temperature readings to stabilize;

5. Press the CAL button for about 2 seconds to enter the correction pH 4.01 mode, and the main display (pH) will flash.

6. Enter the standard value according to the temperature reference table outside the standard bottle (the default value is PH4.01), enter the value with the "up" or "down" key, enter the value, press the "CAL" button for about 2 seconds to complete the pH 4.01 calibration, and the LCD will display the SA screen.

7. Clean the electrodes and dry them with a cotton cloth.

8. Put the pH electrode into the standard solution PH7.0 and repeat for 3~7 steps.

9. Put the pH electrode into the standard solution PH10.01 and repeat for 3~8 steps.

10. Complete 1~9 steps, the LCD will display CAL (main display) and End (secondary display).
