The Dulcometer DMTa 2-wire transducer is a 4-20mA signal converter for pH / ORP / conductivity measurements.
Converts mV signals from pH sensors, etc. into mA signals, enabling long-distance transmission.

In addition, it also supports sensor calibration, and work efficiency can be improved by installing it at the site near the sensor.
In addition, since the signal line and power line are shared, power can be supplied from the connected dulcometer D1C, DAC, PLC, etc., and no on-site power supply is required.

● Water quality measurement in large factories
● mA analog signal output to the centralized control panel
