Hanna Instruments HI8410 Dissolved Oxygen Controller, 0.1 mg/L, +/-1%, -10 to 50 Degree C

The HI 8410 is a panel mounted dissolved oxygen controller that is used to maintain and monitor the concentration of DO in a wide range of industrial process applications. The HI 8410 uses a Galvanic probe that typically requires less maintenance than a Polarographic style making it ideal for long term monitoring. The set point for controlling the activation of a relay is adjusted manually by the user. An alarm relay is also manually adjustable and is based upon a tolerance from the programmed set point. Calibration is single set point and can be done in zero oxygen solution. Specifications: Range- 0.0 to 50.0 milligrams per liter (ppm) O2, 0 to 600 percent O2,-5.0 to 50.0 degree C.
