Wall Mounted EC Digital Controller HI23211

SKU: HI23211-1

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.

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.
