Digital Dissolved Hydrogen Tester 4-in-1 PH ORP H2 Temp Test Kit ppm Meter Water Purity Analyzer for Drinking Water Food Pool

4-in-1 Hydrogen Water Tester – The Yieryi hydrogen tester can simultaneously measure pH, ORP, H2, and temperature, offering a broad measurement range and comprehensive water quality information. Ideal for assessing drinking water, swimming pools, ponds, beer brewing, kombucha, aquariums, hydroponics, laboratories, and food processing.

Accurate Hydrogen Water ppb/ppm Modes – The hydrogen water test pen features two test modes (ppb/ppm), catering to different user preferences. Whether accustomed to ppb or ppm mode, this tester adapts easily with a short press of the MODE/CAL button. It utilizes an upgraded version of the electrode polymer reference for swift and precise readings.

3-Point Calibration – Featuring a high-sensitivity glass probe, the pH meter offers a complete measurement range from 0 to 14 pH with a remarkable 0.01 pH resolution. To ensure accuracy, our pH meter undergoes meticulous three-point calibration using pH solutions at 4.00, 6.86, and 9.18. Our ORP and H2 meters come pre-calibrated for convenience.

Professional Hydrogen Water Tester for Hydrogen Water Bottles – Long-term consumption of hydrogen-rich water can boost metabolism, relieve muscle aches and pains, improve sleep, and bring health benefits to your loved ones. hydrogen tester has a range of 0-2400ppb/0.001-2.400ppm, which can help you quickly get the concentration of hydrogen in hydrogen water bottles, hydrogen water generators, hydrogen water systems, and so on.

Professional pH ORP Tester for Home Use:- 4 in 1 h2 water tester that can measure pH, hydrogen, ORP, and temperature at the same time. It can not only measure hydrogen water but also can be used to test swimming pools, hydroponics, aquariums, saltwater fish tanks, freshwater fish tanks, koi ponds, beer and wine brewing, drinking water, well water, RO water, well water, ponds, aquaculture, Sewage treatment, etc.

Only through electrolysis, the hydrogen in the water will be released to form H2, so tap water or drinking water can not be directly measured to PPM or PPB, please electrolyze the water and then measure it, or measure the water in the hydrogen-rich cup.pH Meter for Kombucha

Kombucha is processed at a pH of 2.5-3.5, ensuring that the starting pH for the first fermentation of kombucha is 4.5 or less. Whether you are making kombucha, beer, vinegar, water kefir, etc., these pH testers are an ideal tool for the home brewer.

How to Calibrate the pH ?

1. Before calibration, prepare 3 beakers containing separately 250ml of pH 4.00/pH 6.86/pH 9.18 standard solution.

2. Rinse the electrode with clean distilled water and wipe it dry. Turn on the pH meter and adjust to pH mode.

3. Immerse the electrode into the pH6.86 buffer solution, wait for the value to stabilize, press “CAL” for 5s, and the screen will display “CAL”, when pH6.86 flashes 3 times, the calibration of pH6.86 is finished.

4. Repeat the above steps to calibrate pH4.00 or pH9.18.
