The content of dissolved hydrogen in water has become one of the indicators for determining hydrogen-rich water. The hydrogen content value can be read by putting the hydrogen detection pen directly into the hydrogen-rich water, which is convenient for detection and easy to carry. YY-400H hydrogen content detection pen is developed for measuring the dissolved hydrogen content in hydrogen-containing water generators and generators, and measures the dissolved hydrogen content in water bodies. Suitable for hydrogen-rich water machine, hydrogen-rich water cup, hydrogen water stick, hydrogen-rich kettle, etc.

1. YY-400H can measure H2 (0-4000PPb；0-4.000 ppm) and temperature (0.1-60.0°C; 32.0-140°F) with high accuracy. Comprehensive measurement of water quality to ensure healthy water quality.

2. Accurate measurement: In order to achieve high precision, it is equipped with high-quality titanium alloy probes and reliable automatic temperature compensation (ATC) to ensure that accurate readings can be maintained at different temperatures.

3. Automatic shutdown function: automatically turn off the power, automatically turn off the power after 5 minutes, without any operation to save power.

4. IP67 waterproof rating: IP67 is an international waterproof and dustproof certification. Dustproof and dustproof, soak for a short time.

5. Wide range of applications: water quality detectors are suitable for water quality detectors, swimming pools, aquariums, hot springs, hydroponics, laboratories, drinking water, etc.
