Description

DESCRIPTION

HI-8720 Panel mounted ORP analogue controller with self-diagnostic test, range: +/-1999 mV

This instrument allows the selection of a set point for oxidising or reducing dosage.

When used in conjunction with the HI-8710 pH controller, the ODCD (ORP dosing consent device) function (featured by the HI-8710) will ensure that the ORP dosage will start only when the pH level is correct.

These instruments have been designed for easy and fast installation and are provided with membrane keypads on the front panel, large display, and auto-diagnostic functions.

Each model accepts either a direct input from an ORP electrode or from a transmitter through 4-20 mA input. The instrument also provides ±5V power output and input terminals for amplified electrodes.

Moreover, you can choose the output configuration for connecting a recorder or a PLC, between 0–20 or 4-20 mA.

A removable, transparent splash-proof cover protects the front panel.
