Measuring and control device DULCOMETER Compact

The measuring and control device DULCOMETER Compact for pH and redox measured variables is equipped with the standard functions for use in water treatment plants, allowing the operator to switch between the measured variables pH and redox, and between P and PID control characteristics.

Product description

Compact Measurement and Control!

The ProMinent DULCOMETER Compact analyzer provides precise measurement and control of pH or ORP process variables. The pre-configured Compact can be programmed for either pH or ORP control without having to purchase a separate analyzer. Temperature compensation for pH can be added using an optional PT 1000 sensor. The Compact comes standard with pulse relay for pump control, configurable analog output, and configurable power relay.

Features and Benefits

  • Switch between measured variables pH and redox
  • pH sensor monitoring
  • P or PID control characteristics
  • Temperature compensation of the pH value by temperature sensor input (Pt 1000)
  • Compact universal housing
  • Illuminated display with three LEDs
  • Pulse frequency relay for metering pump control
  • Power relay can be configured as an alarm, limit value or pulse
  • Analog output 4-20 mA can be configured for measuring or control output
