HI-23211-2 Industrial Grade EC Digital Wall Mounted Controller information

Hanna's extended description

HI-23211-2 Industrial Grade EC Digital Wall Mounted Controller


  • CAL Check™ – Alerts users of calibration status
  • ATC – Automatic temperature compensation

The Industrial Grade EC Digital Controller is a wall mounted, microprocessor conductivity controller that provides very accurate measurements due to the four-ring EC probe and automatic temperature compensation (ATC Feature).

Users can choose from models featuring on/off or PID control, analogue/RS485 output of 115V or 230V, and dual set point. The relay contacts can drive external devices such as pumps or electro-valves.

The input signal can come from a probe or a 4-20mA transmitter. Models with the RS485 output option are also available. This option allows the user to insert the controller into a 2-wire RS485 network. The controller measures 221 x 181 x 86mm (8.7 x 7.1 x 3.4 inches) and weighs 1.6kg (3.5lb).

EC Range 0.0 to 199.9 μS/cm, 0 to 1999 μS/cm; 0.00 to 19.99 mS/cm; 0.0 to 199.9mS/cm.

The HI-2X range help to prevent overdosing or costly system failures and a fail-safe protection alarm protects processes against critical errors arising from power interruptions, surges and human errors.

A password protection feature keeps the controllers safe from tampering.

The wall mounted controllers have mounting holes moulded into the housing to assure simple, quick and secure installation without the need for additional hardware. Pumps and temperature electrodes can be installed easily.

In general, the compact, easy-to-use controllers are designed to consistently perform in most environments and conditions twenty-four/seven.

There is no need to worry about space or cost, as all the controllers can be installed in confined spaces and the low cost means previously manual monitoring can now be automated, saving time and money.

The controllers have large, easy-to-read displays, fire-retardant casing, proportional control, full PID Control, password protection, analogue or digital transmitter input, data logging, programmable cleaning cycles and fail safe alarm systems.

Wall-Mounted Process Controllers

Simple to Use

The large, dual-level LCD shows both primary measurement and temperature and guides operators through calibration and programming with step-by-step prompts. The choice of ON/OFF, proportional and PID control provides extra versatility and makes it possible to pick the process controller that best fits your application. Keeping track of multiple controllers in different plants is made easy. These advanced controllers can be identified with both a factory and process ID.

Fail Safe Protection

The Fail Safe Alarms protect processes against critical errors arising from power interruptions, surges and human errors. The sophisticated yet easy to use system resolves these problems on two fronts: hardware and software. To eliminate blackout and line failure problems, the alarm function operates in a “normally closed” state and goes off if the wires are accidentally tripped, or when the power is down. This is an important feature since with most meters the alarm terminals close in abnormal situations, but no alarm is sounded with a line interruption, causing extensive damage. With our controllers, software is employed to set off the alarm in abnormal circumstances, for example, if the dosing terminals are closed too long a red LED will provide a visual warning signal.

Differential Input (Matching Pin)

All Hanna controllers in this family come with a differential input to prevent problems due to ground loop current. With this new feature, the life of the electrodes will be greatly extended.




Save Money with Custom Programs

HI-23 help to prevent overdosing or costly system failures. You can set your high and low set point hysteresis bands independently to fine tune dosing processes with the ON/OFF controllers. Similarly, the proportional band and time period are user-programmable to save on slow reacting chemicals which are commonly overdosed.

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.

All models offer an adjustable overdosing timer from 10 minutes to 7 days as the maximum time that the relay contacts may remain closed - An important feature in case of sudden chemical depletion, truncated intake or discharge tubing and other calamities.

Simple Installation

These wall mounted controllers have mounting holes moulded into the housing to assure simple, quick and secure installation without the need for additional hardware. Once all electrical connections are made, the protective cover can be installed over the front panel, making it possible to perform all adjustments without disassembling any part of the unit. Temperature probes can also be installed. Pumps to be used in conjunction with the controller simply plug into the controller’s input and will be powered up through the unit’s internal power supply.

Mechanical Dimensions

The modular design isolates electrical connections in a closed compartment, while the control settings are accessible and can be made through the adjacent compartment.
