C6587 Conductivity Controller

C6587 Conductivity Controller

The C6587 Conductivity Controller allows for effective measurement and control of electric conductivity and total dissolved salts. The sensors and submersible probes in our range of products allow for the visualization of the temperature value, making the controller suitable for any type of application and installation.

The C6587 has a monochrome multi-line graphic display that displays the values of the measures such as in %, ppt, ppm, ppb, g/l, mg/l, μg/l, Bè or a custom unit (4 characters max) and displays messages which guide the user through the easy and guided initial set-up, configuration and during normal operation. There are dedicated keys to directly access zero and sensitivity calibration as well as to aid with configuration of the device.

Key Features

The model C6587 is a microprocessor surface mounting conductivity & oC instrument featuring a multilinegraphic display. Which displays the measured parameter & solution temperature if a temperature sensor is available, or the base temperature selected if no temperature sensor is available.

The display shows the state of the control and alarm relays. The model C6587 maybe user configured to display conductivity in μS or mS depending on the range selected, TDS (Total dissolved solids) user configured conversion factor 0.45 to 1.0 TDS/Conductivity. Resistivity in M! for ultra pure water with the special temperature compensation required for UPW.

The temperature sensor provides both automatic temperature compensation and a solution temperature readout. The automatic temperature compensation has both user selectable base temperature and temperature coefficient in % per oC. Two isolated current outputs of 0 - 20 mA or 4 - 20 mA are available which maybe user configured for either 2 x conductivity or conductivity & oC. The control relays can be programmed for either On/Off control, PFM control to proportionally control electronic metering pumps or PWM to time proportionally control solenoid valves or small pumps. One adjustable alarm relay with delay timer is fitted which operates on both a high and low measured value. Two logic inputs are available which inhibit the operation of the control and alarm relays so the instrument goes into a standby mode when operated. Designed to IP65 for outside installation to provide reliable accurate and dependable measurement and control of many industrial process.


The C6587 Conductivity Controller is useful for a wide variety of applications including the chemical industry, electroplating, food and beverage, water treatment and many more, If you’re concerned about your application and need expert help, call us today and one of our team will be able to help you with your needs.
