DH Test Reagent

DH is a measurement for the amount of Dissolved Hydrogen molecules in water.
We use PPB(Parts Per Billion) as a figure of DH level, and it starts from 0.

0 means that here is no hydrogen in the water.
If it goes up to 1,000 PPB, it means there are 1L of hydrogen in 1µg water.
Generally, we call it “Hydrogen water” only if DH level goes more than 1,000 PPB.

Easy to use

Customers can test the DH level of hydrogen water much more easier than before.

Just grab the reagent, open & test it, then discard it.


The former type of DH reagent generally is not accurate. Since it meets oxygen every time we open the lid, there could be some changes in chemical composition.

IonFarms WATER TEST KIT ensures the best accuracy.


Since DH reagent is chemical compound, It is highly sensitive to storage environments.

With IonFarms DH reagent, you don’t have to worry about storage.


※ Do the test with water temperature of 25~35℃

① Shake the reagent well for the components to mix properly before starting the test.

② Pour the hydrogen water to be tested until the indicated line of the provided test bottle.

③ Make 7 drops of reagent to the bottle.

④ If the reagent drops turn transparent, start adding 1 drop at a time.

⑤ The water contains 1,000ppb ~ 1,100ppb if they turn blue on the 11th drop.

* Slightly shake the test bottle every time the reagent is dropped.
* DH test results may vary depending on the environment. Use the hydrogen meter for exact results.
* For more exact results, do the test after running the cleaning mode.
* Do not reuse the reagent once opened.
* You may refer to our video below for the details.
