Controller DULCOMETER Compact

As a controller in water analysis, the DULCOMETER Compact is the correct controller for control tasks that require only a 1-way control.

Product description

Compact yet fully equipped - the basic water analysis unit

The DULCOMETER Compact controller is a one-channel PID controller Controls processes automatically to ensure that the specified values (e.g. pH: acid or alkaline) are maintained even in the event of interfering influences. more in the glossary for the measured variables The physical variables to be determined by measuring. more in the glossary pH, ORP, chlorine and inductive conductivity. It can monodirectionally control the measured variable, monitor limit values and transmit the measured value via an mA output, e.g. to a PLC. The mA output can optionally also be configured as a controlled variable output. The controller has one pulse frequency output to control one metering pump. One output relay can optionally be used as an alarm or limit value or to control motor-driven metering pumps or solenoid valves. A digital input is used to switch off the control or to process a sample water limit contact by remote control. The impact of temperature on the measurements can be provided by temperature measurement or by manual input. Menu-driven operation is language-independent.
