tester pH-009

Image
This device is designed to measure the acidity of water or other solutions Operation: - remove the protective cap - first rinse the electrode with distilled water, and suck it with filter-paper - turn on pH by "ON-OFF" switch located on the top of battery case - immerse the pH meter electrode in the solution to be tested - sir gently and wait for the reading to stabilize - after use, switch OFF pH, Use the distilled water clean the electrode and replace the protective cap pH calibration: - immerse the electrode in pH 6.86 standard buffer solution  of phosphate, and gently shake the electrode - regulate the trimmer with a screwdriver until the buffer solution value corresponding to the measurement temperature is obtained - immerse the electrode in pH 4.01 or pH 9.18 the standard buffer solution  of borax
