PH Controller SUP-MDC-PH smart, online pH/ORP transmitter

The MDC-PH Controller is a smart, online pH/ORP transmitter. Its multi-mode channel functionality allows for the connection of both analog and digital sensors. Continuous monitoring data can be transmitted to a DCS system via output connections for remote tracking and recording. Alternatively, communication with computers is possible through an RS485 interface using the Modbus-RTU protocol, enabling computer-based monitoring and recording.
