Fail Safe Alarm System

Hanna’s exclusive Fail Safe Alarm System protects against problems caused by power supply failure or signal interruption, which are typical risks in industrial environments. An alarm condition is indicated by a red LED, located directly on the front panel of the controller.

Isolated Recorder Output

To enhance troubleshooting and the ability to record data while monitoring, simply attach a recording device to the instrument’s 4 to 20 mA output contacts, conveniently located on the front panel, to obtain a copy of the results on demand.

Quality Construction

Housed in a rugged, modular, fiber-reinforced polypropylene housing that will resist the harmful effects of most chemicals.

Simple Installation

HI21211 has mounting holes molded into the housing to assure simple, quick and secure installation without the need for additional hardware.

Matching Pin

A differential input prevents problems due to ground loop current, extending the life of the electrodes.

Password Protection
