PH meter acidity meter precautions:
(1) Please avoid high temperature, direct sunlight
(2) Do not touch the sensor, if you do, please rinse it with a buffer solution with a pH of 7
(3) After each use, please close the cap
(4) Do not test in high temperature liquid for too long
(5) Please rinse the sensor after use in a solution with a higher TDS value
(6) If the measurement range of the pH solution is very different, it needs to be washed in a buffer solution with a pH of 7.
(7) To optimize performance, use the best measurement accuracy at least once a month
(8) Although unnecessary, the ph pen will be more accurate if it is calibrated before each use
(9) Rinse with a buffer solution with a pH of 7 after each use
(10) When using, be sure to shake out the air bubbles inside
(11) If the sensor is scratched, it needs to be replaced immediately
(12) If the reading is slow or the response is slow, the pH meter battery or sensor needs to be replaced. If the pH pen is continuously used and calibrated, the performance will be affected. If the pH pen is operating in a suitable environment, press the temp/cal key, when the cal When flashing, press the temp/cal and hold keys simultaneously for 2 seconds to restart the calibration, and then you can recalibrate
