"Hanna Mini TDS panel-mounted controller; 0-49.9 mg/l; 12 VDC adapter"

BL 983318 is a mini-controller designed for easy, affordable installation in small spaces, ideal for simple but effective process control.

The BL 983318 has ATC (Automatic Temperature Compensation) and simple one-point calibration.

The multi-coloured LED continuously indicates whether the mini-controller is in measuring, dosing or alarm status.

All wiring and connections to external devices are extremely easy to perform via the outputs at the rear of the instrument.

You can also choose between automatic or manual dosing mode with a switch at the front.

Manual control is particularly useful during maintenance work, as it allows you to switch the dosing relays on or off according to your needs.

A time control system advises you if the relay is active for too long, to help prevent overdosing.
