Peristaltic Dosing Pump

The powerful built-in peristaltic pump uses a stepper motor which does not have any gears or brushes, for a long life with minimal maintenance.

Automatic Proportional Pump Control

The peristaltic dosing pump is controlled by a simple on/off option, or through an advanced proportional control to help prevent overshooting the set point.

Adjustable Flow Rate

The dosing pump flow rate is adjustable from 0.5 to 3.5L/h, to better maintain a desired set point.

Acid Tank Level/Flow Switch Input

A connection to an optional level controller or flow switch that can be used to disable the dosing pump when the chemical reservoir tank is empty or there is no flow when the pump is turned off.

Multicolored LCD Display

A multi-colored LCD shows the status of the controller. The display is green during normal operation or red if an alarm is triggered.

Quick Connect Probe Input

The Quick Connect DIN connector creates a waterproof seal with the meter, reducing electrical noise issues with the connection caused by humid environments.

GroLine pH/Temperature Probe

The HI981412 uses the HI10063 amplified probe that incorporates both pH and temperature sensors and connects to the controller with a single waterproof Quick Connect DIN connector.

Built-in amplifier
PVDF body
1/2” threaded fitting for insertion to an in-line “T” fitting or the flow cell
