Hydrogen Water pH ORP Meter YG-400 Digital Drinking Water Tester with Temperature Display for Home Health and Alkaline Water Use

Hydrogen Water pH ORP Meter YG-400 Digital Drinking Water Tester with Temperature Display for Home Health and Alkaline Water Use

Feature

1. Safe Drinking Starts Here – 4-in-1 Water Quality Meter
The YG-400 is a multi-function drinking water tester designed for home use. It precisely monitors pH, ORP, hydrogen concentration (H₂), and temperature in your water, helping you detect impurities and ensure safe hydration for the whole family.

2. Know Your Water: Ideal pH for Health is 7.0–8.5
Water with a slightly alkaline pH (7.0–8.5) is considered healthiest for drinking. It supports better metabolism and reduces acidity in the body. YG-400 delivers ±0.01 pH precision so you can stay within the perfect health range every day.

3. The Power of Hydrogen Water – Natural Antioxidant
This hydrogen-rich water tester lets you measure dissolved H₂ in ppb/ppm. Hydrogen water is known for neutralizing harmful free radicals, promoting cellular health, and improving overall energy levels. Ideal for people pursuing a wellness-focused lifestyle.

4. Fast Calibration, Auto Temp Compensation, Plug & Play
Supports 3-point calibration (pH 4.00/6.86/9.18) and automatic temperature compensation (ATC), ensuring accurate readings in all conditions. Just dip and test—perfect for daily water checks at home, office, or travel.

5. Portable, Backlit & Family-Friendly Design
This compact digital pH ORP meter features a bright LCD backlight and easy-to-press buttons. It’s ideal for elderly users, children, or health-conscious adults. Take control of your family’s water health—anywhere, anytime.

Note

Ordinary tap water has almost no hydrogen, so the test result is 0. Only the prepared hydrogen-rich water can be tested, and the device will display the hydrogen value normally.
