11. General Information
1.Product Overview
DH30P is designed based on polarography principle. Hydrogen molecule in hydrogen
water enters the electrode chamber filled with electrolyte through selective
semipermeable membrane of electrodes. Under polarization voltage between
anode and cathode, current related to the concentration of dissolved hydrogen is
generated. With temperature compensation, the concentration value of dissolved
hydrogen is obtained.
The measurement range of this DH30P is up to 8 ppm. It can be assured to selectively
measure dissolved hydrogen without interference from other reducing substances.

5. Battery and Electrode installation
Unscrew the screw cap by following the
arrow direction, slightly unplug the
electrode, install the battery(pay attention
to the anode and cathode of the
electrode).
Then install back the electrode and the
