Electrolyte for the Hanna Oxy-Check D.O. Meters
Product Code: HI7042S
The Hanna HI7042S Dissolved Oxygen Electrolyte Solution is a high-quality refill solution formulated specifically for Hanna galvanic dissolved oxygen (DO) probes. Supplied in a convenient 30 mL dropper bottle, this reagent-grade electrolyte restores the internal electrolyte of galvanic DO sensors, ensuring accurate dissolved oxygen measurements and reliable probe performance. Using the correct electrolyte is essential for maintaining sensor sensitivity, response time, and measurement accuracy.
Galvanic dissolved oxygen probes contain a zinc anode and silver cathode immersed in electrolyte behind an oxygen-permeable membrane. As oxygen diffuses through the membrane, it reacts within the probe to generate an electrical current proportional to the dissolved oxygen concentration. Replacing the electrolyte as part of routine probe maintenance helps maximize sensor life and measurement reliability. HI7042S is manufactured using reagent-grade chemicals and is supplied in a sealed dropper bottle for clean, precise filling.
