SUP-PH8.5 pH/ORP Controller

SUP-PH8.5 is an intelligent online pH/ORP analyzer featuring a mixed-channel mode that supports the connection of either analog or digital sensors. Continuous monitoring data can be transmitted to a DCS system via the output signal for remote monitoring and recording, or communicated to a computer using the Modbus-RTU protocol over an RS485 interface, enabling computer-based monitoring and data logging.
