Hanna Instruments HI9147 Portable Galvanic Dissolved Oxygen Meter

Aquaculture applications call for the robust, water-resistant dissolved oxygen (DO) meter known as the HI9147. The meter and probe employ galvanic sensor technology, in which the reaction is powered by the potential difference between the electrodes and does not require an external voltage. The mechanism establishes a current proportional to the concentration of dissolved oxygen present as oxygen diffuses across the membrane. A galvanic, HDPE membrane caps, electrolyte fill solution, a shield, and a reliable carrying case are included with the HI9147.
