Hanna Instruments-8410 Panel Mounted Dissolved Oxygen Controller
he Hanna Instruments-8410 is an extended range panel mounted Dissolved Oxygen (DO) controller that is used to maintain and monitor the concentration of DO in a wide range of applications from wastewater treatment to aquaculture. The HI 8410 uses a Galvanic probe and typically require less maintenance than a Polarographic style making it ideal for long term monitoring of aeration basins, ponds, and lakes.
The set point for controlling the activation of the 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.
The dosage mode: Automatic, Continuous ON or OFF and over dose control by setting the Overtime dosage trimmer. If the dosing relay remains continuously activated for more than the selected dosing time, the alarm relay is activated, the alarm LED will start blinking and the dosing relay will be deactivated. A jumper found on the rear panel can disable the “Over time dosage” function.
Automatic/Off/manual dosing selection switch and LED on the front panel.
In Automatic mode all the relays are controlled based on the measurement set point and alarm values. In OFF mode the dosing and alarm relays are always deactivated. The dosing LED is OFF (as relay status) and the ALARM LED is in accordance with the instrument set point, input reading, and ALARM.
In ON (Manual) mode the dosing relay is always on. The alarm relay is still enabled. If an alarm occurs the dosing relay remains activated. If the over dose time exceeds the setting during manual mode, the alarm relay remains activated.
The front panel is protected behind a transparent splash-proof cover.
