HI2321 is a wall mounted, microprocessor conductivity controller specifically designed to meet your process control requirements. This controller provides very accurate measurements due to the four-ring EC probe and Automatic Temperature Compensation (ATC) feature.
- Fail Safe Alarm System.
- CAL Check™ alerts users of calibration status.
- Four-ring method provides an exceptionally stable measurement over a wider range.
Details
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.
Simple Installation
- HI22111 has mounting holes molded into the housing to assure simple, quick and secure installation without the need for additional hardware.
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.
Good Laboratory Practices (GLP)
- The GLP feature allows users to store and recall data about system status for ultimate traceability.
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.
