Distilled or deionized water (8-16oz) for rinsing the probe after each test b) Tissue paper for drying the probe 3) For PH60-Z and PH60F-Z testers: a) A few drops of water are added to the probe cap to keep the pH electrode in an activated state before the tester leaves factory.
6 pH Calibration 6.1 Calibration Steps 1) Short press to turn on the meter; rinse the probe in distilled water, shake the meter in the air and use tissue paper to dap off excess water (never rub or wipe the sensor tip). 2) Pour certain amount of pH 7.00 and pH 4.00 buffer solution into the corresponding calibration bottles (to about half volume of the bottle);...

3) For pH Calibration buffer solutions, we recommend that users replace new buffer solution after 10 to 15 times of use to keep the standard buffer’s accuracy. Do NOT pour the used calibration solutions back into the solution bottles in case of contamination. 4) When calibrating strong basic solutions (pH>10), use 7.00 pH and 12.45 pH to calibrate;...
Solid samples such as cheese, meat, fruit, vegetables, sushi rice, sensor bread, and soil; also works well for general water solution. Flat surface measurement such as skin, paper, fabric, leather and PH60F-Z – Flat glass so on; micro sample testing; also works well for general water membrane solution.
3) PH60F-Z Flat probe testers are mostly for flat surface sample test. a) For skin test: skin should be without sweat or dirt, nor be overly cleaned (do not use facewash products before testing) to avoid affecting measurement results, dampen skin with some distilled water, slightly force flat probe onto the skin, get readings after value stabilized.
2) Auto. Lock (P02) – Users can set the auto lock time from 5 to 20 seconds. For example, if 10 seconds is set, when the measured value is stable for more than 10 seconds, the measured value will be automatically locked, and the HOLD icon will be displayed. Short press release the lock.
