4.3 Calibration Information Table - 3 pH standard buffer solution series pH standard buffer solution series Icons USA series NIST series 4.00 pH 4.01 pH Three-point calibration 7.00 pH 6.86 pH 10.01 pH 9.18 pH 4.3.1 Three-point calibration The instrument can perform 1-3 points calibration. The first point calibration must use 7.00 pH (or 6.86 pH) standard solution, then select other standard solution to perform the second and the third point calibration. -

4.4 pH Meter Calibration (with an example of three-point calibration) 4.4.1. First point calibration (a) Press key to enter into the calibration mode, “CAL 1” blinks at the top right of LCD and “7.00 pH” blinks at the bottom right of LCD, indicating using pH 7.00 buffer solution to make the 1 point calibration. -
Page 11: Sample Test
4.5 Sample Test 4.5.1. Rinse pH electrode in distilled water, dry it, and submerge it in test solution. Stir the solution briefly and allow it to stay in the tested solution until icon appears and stays on LCD. Then get the readings of the measurement. - Page 12 4.5.3 pH Isothermal Measurement Principle According to the pH isothermal measurement principle, the closer the test sample’s temperature is to the calibration solution’s, the higher the accuracy of the measurement. This principle is recommended to follow when conducting tests for the best result. Example: If users were to test samples at 150˚F, we recommend warming up the calibration solutions to the same temperature before performing calibrations in order to get the most accurate readings.
