Precautions for pH Meters (Acidimeters)
(1) Please avoid high temperatures and direct light exposure
(2) Do not touch the sensor. If touched, rinse with a buffer solution with a pH of 7
(3) After each use, please cover the pen cap
(4) Do not test for too long in high-temperature liquids
(5) After use in solutions with high TDS values, please rinse the sensor
(6) When measuring solutions with significantly different pH ranges, it is necessary to rinse them 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, calibrating the pH pen before each use would be more accurate
(9) Rinse with pH 7 buffer solution after each use
(10) When using, be sure to shake out the bubbles inside
(11) If there are scratches on the sensor, it needs to be replaced immediately
(12) If the reading is slow or the response is sluggish, the acidity meter battery or sensor needs to be replaced. If the pH pen is continuously used and calibrated, its performance will be affected. If the pH pen operates in a suitable environment, press the temp/cal button. When cal flashes, press both the temp/cal and hold buttons for 2 seconds to restart calibration, and then recalibrate.
