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 attaches 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.
Good Laboratory Practices (GLP)
The GLP feature allows users to store and recall data about system status for ultimate traceability.
Simple Installation
HI22111 has mounting holes molded into the housing to assure simple, quick and secure installation without the need for additional hardware.
Quality Construction
Housed in a rugged, modular, fiber-reinforced polypropylene housing that will resist the harmful effects of most chemicals.
Password Protection
The Hanna password protection feature keeps these controllers safe from tampering. Only users with the proper password can change the settings of these controllers.
