GAOMON Digital PH Tester 0.01 Resolution High Accuracy 0-14pH

Color LCD Screen Design Compared with other monochrome backlit screen test pen, ours is updated and upgraded version with a colored screen LCD design, which makes every reading clear and easy to read and not easy to be confused. When pH value is lower than 2 or higher than 12, the reading on screen will turn red to remind you. Sensitive Bulb Built Our core of the pH meter is electrode and the core of the electrode is bulb. The digital pH tester bulb made by blue effect technology is blown at high temperature of 1000℃. This design can fully respond to H+ ions in the solution.The bulb glass film uses a low-impedance glass sensitive film and the reaction speed is also improved, reaching a true level of 0.01 resolution. ATC Accurate Calibration Thanks to built in automatic temperature compensation (ATC), which can accurately determine pH value of the sample at any temperature in a range of 0℃- 60℃ (32℉ - 140℉), you can get the accurate pH value without t
