The local controllers are powered by 110/220 Vac and automatically recognize the connected sensor via serial interface and Modbus 485 protocol.
They have the functions necessary for the configuration and local storage of the acquired data; the single-parameter controller has a 4-20 mA analog output, while the multi-parameter controller can be optionally integrated with external analog-digital interface modules.
Both controllers also have a serial output with Modbus 485 protocol to external plant units (PLC, data logger).
The portable controller is battery powered and can manage a sensor or probe for use in the field.
SH-WMC-200 water quality monitor with automatic sensor recognition and real-time display of measured values ​​and sensor status. The monitor can calibrate the sensor and includes data storage and remote transmission functions. Its simple interface and easy operation make it quick and easy for even non-professionals to use.
