Product Description
DH30 Dissolved Hydrogen Tester
DH30 Dissolved Hydrogen Meter : To measure Hydrogen Rich water, Dissolved Hydrogen concentration in the Hydrogen water generator.DH30 is designed based on ASTM Standard Test method. The precondition is to measure the concentration of dissolved hydrogen at one atmosphere for pure dissolved hydrogen water.
The method is to convert the solution potential into the concentration of dissolved hydrogen at 25 degrees Celsius. The measurement upper limit is around 1.6 ppm.
This method is the most convenient and fast method, but it is easy to be interfered by other reducing substances in the solution.
Application: Pure dissolved hydrogen water concentration measurement.

Notice
1.Please keep the metallic diaphragm always clean.
2. Please rinse off the sensor tip with clean water after each use and cover the protection bottle back. Please also check the volume of the soaking solution. If not enough, please be sure to add more. Note: After each use, if there is some moisture or solution liquid on and near the metallic diaphragm, random numbers may get displayed. Rinse off the tip with clean water and place it back in sensor protecting cap. Make sure it displays"0" before shutting off power.
3. If there is smudginess and mineral elements adhere on the metallic diaphragm, the responsive time will be deduced and readings might drop. Please use the wiping paper to polish the electrode metallic diaphragm. Make sure the sensor tip is very clean. After cleaning, please must keep the sensor tip in soaking solution. If the reading is not 0.000ppm when in soaking solution, please change the sensor.
4. Life expectancy of an electrode depends on frequency of use. Generally, it should be replaced in 1 year.Generally, it should be replaced in 1 year.
Cleaning order of the electrode metallic diaphragm:
1. Spin off the sensor protection bottle (please pay attention not to spill out the soaking solution).
2. Hold the wiping paper (with the rough surface up) and drop a few drops of water on the paper.
3. Horizontally contact the bottom of the metallic diaphragm with the wiping paper which having water on it. Rub rotating as you writing the Arabic numeral "8" for around 10 times.
4. Rinse off the tip with clean water and place it back in sensor protecting cap. Make sure it displays"0" before shutting off power.
Before measuring, please polish the electrode metallic diaphragm with the wiping paper. When measuing, please stir the electrode properly.
