The ECD Model T80 transmitter is a single- or dual-channel, intelligent, multiparameter transmitter designed for the online continuous measurement of pH, ORP, pION, dissolved oxygen, conductivity, resistivity and turbidity in a general-purpose industrial environment. The Model T80 transmitter digitally communicates with any ECD S80 digital sensor, automatically configuring the transmitter’s menus and display screens to the measured parameter. The Model T80 transmitter can be loop-powered, 24-VDC-powered or 100 to 240-VAC-line-powered. The standard configuration has a 4-20-mA output and a RS485 serial communication port with MODBUS RTU output. A HART communication version (single-channel version only) is also available. Alarm relays are optionally available on either line-powered transmitter.
