+ BL932700-0: uses 12VDC adapter

+ BL932700-1: use 115/230VAC power source

DOSING RELAY

The dosing relay can be set to dose above or below the user-programmable pH set point.

OVERDOSE PROTECTION

Can be programmed to shut off a valve, pump, or connected device when continuously activated beyond a selected time; Adjust from 5 to 30 minutes.

CONTROL MODE SWITCH

With just one switch, normal “Auto” operation can be converted into “ON/OFF” mode.

ANALOG OUTPUT

4-20 mA analog output for connection to data logger, chart recorder or other device.

PROTECTIVE DOSING

The mini controller is protected against a maximum of 2A load from one pump or connected device.

EASILY CONNECT PERIPHERAL DEVICES

Easy terminal connection to power, communications, dosing control, or sensors.

MATCHING PIN

Protect sensors from ground loops to avoid disturbing measurement results or damaging the system.

BNC

The monitor can connect to any pH electrode with a BNC jack.
