Hanna Mini ORP Panel Mount Controller with Analogue Output - 220/240V

BL 932700 is a mini-ORP controller designed for easy, affordable installation in small spaces, ideal for simple but effective process control.

Thanks to its compact size, the BL 932700 can be installed right next to reservoirs and vessels.

This versatile controller is ideal for a wide variety of applications, such as ORP control bleaching processes, waste water treatment and swimming pools.

The BL 932700 allows automatic control of installations that were previously controlled manually.

The instrument can be set to a reducing or oxidising dose. It measures in the range of 1000 mV, with 1 mV resolution.

Adjustment and calibration of the set value are easily performed by trimmers on the front panel.

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

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 when the relay has been active too long, to help prevent overdosing.

In addition, this model has a 4-20 mA analogue output for recording purposes.
