pH Meter for Water Portable pH Tester Digital

ph meter for water Affordable and useful for those who need a water testers for drinking water? aquariums?Spa and pool water use If you want to know how to control the digital ph meter of hot spring and hydroponic you can accurately measure it with a ph water tester to help you avoid using water that is harmful to your health One of the most common concerns of breeders is pH. The right ph value can provide a better growth environment. water quality tester Calibrated at the factory. If it is not used for a long time or the reading is not accurate please follow the steps below to perform a calibration How to use the calibration solution: Wash the pH meter electrode with pure water (2-3 times) 1.Immerse the pH electrode in a mixed phosphate standard buffer solution with a pH of 6.86 (at 25 ° C) and shake gently 2.Press and hold the calibration button. Do not let go after the value starts to jump Keep pressing until the value is displayed at 6.86 3.Rinse the electrode with purified water first,and then insert the electrode into a standard potassium phosphate dibasic phosphate buffer solution with a pH of 4.00 for calibration 4.After about two minutes. The displayed value should be within the tolerance range compared to the pH value of the buffer solution The so-called two-point calibration is to use two kinds of calibration solutionsCalibration is generally started from 6.86. Then using 4.00 Specifications Measure range: 0.00- 14.00PH OperatingTemperature: 0°F - 140°F?0?-60?)
