Hanna Instruments BL 983327-1 Mini pH Controller

Hanna Instruments BL 983327-1 Mini pH Controller

The BL983327 is a compact, panel-mounted process controller for measuring the conductivity of a process stream. It features a large LCD display with a protective cover. The user can select between automatic and manual dosing modes. In automatic mode, the dry contact relay activates when the measured value exceeds the setpoint. This relay can be used to activate a solenoid valve to open and drain a tank (e.g., to vent and feed a boiler) or to add fresh water until the desired setpoint is reached. The BL983327 is a similar product, offering the same measurement range, but with a relay that activates when the measured value falls below the setpoint. Multicolor LED indicator: the LED changes color depending on the status.
