Portable Digital ATC PH Meter 0.00~14.00 Water Fish Tank Monitor Water Quality Solution Analyze r LCD Glass Electrode
How to use:1. 1 bag 6.86 PH buffer powder  needs 250ml water(Distilled water, Pure water, water with PH value neutral in room temperature), then shake it gently, then use the pen to test it. If it display 6.8, then the pen is good to use.2. If not, please use the screw to calibrate it ( The hole in the back ) , until the value is 6.83. If use 4.0 powder to calibrate, the test result need to be 4.0, and the pen need to stay in the water Note:The PH meter need to be recalibrated, when:1. the PH meter has been used or placed for a long time2. the PH meter has been used frequently3. High accuracy is needed How to use Take the electrode cover off before use Press the ON/OFF key, place the electrode into the solution to be tested;After the value is stable, press the HOLD button to take out and reading;After finished, press the ON/OFF key, wipe the electrode clean, and insert the electrode protection Cover;
