【High Accuracy & More Sensitive Bulb Design PH Meter】: The core of the ph tester digital is the electrode, and the core of the ph tester electrode is the bulb. The ppm meter bulb made by blue effect technology is blown at a high temperature of 1000 degrees Celsius. This can fully respond to the H+ ions in the solution.The bulb glass film uses a low-impedance glass sensitive film (≤25MQ), and the reaction speed of the TDS PH meter is also greatly improved, reaching a true level of 0.01 !
【PPM Meter with One Key Lock Value Function 】: When the measured value is stable, just press the HOLD/TEMP key to lock the measured value and take it out for viewing, which is really simple.
