The HI9147 is a rugged, water-resistant dissolved oxygen (DO) meter designed for aquaculture applications. The meter and probe use galvanic sensor technology where the electrodes’ potential difference drives the reaction, requiring no external voltage. Oxygen diffuses across the membrane and the system establishes a current proportional to the concentration of dissolved oxygen present. HI9147 comes with a galvanic, HDPE membrane caps, electrolyte fill solution, a protective shield, and sturdy carrying case.
- – Easily Replaceable Membrane Caps
- – Manual Calibration
- – Galvanic Measuring System
