Details:

HI7042S is designed to refill the electrolyte solution for galvanic dissolved oxygen probes. Galvanic sensor technology requires no external voltage since the difference in potential between the cathode and anode is greater than 0.5 volts. Galvanic DO sensors consist of two electrodes, a zinc anode and silver cathode, both of which are immersed in electrolyte solution. An oxygen permeable membrane separates the anode and cathode from the water being measured. Oxygen diffuses across the membrane and interacts with the probe internals to produce an electrical current that is proportional to the concentration of oxygen in a solution.
