UNIVERSAL TRANSMITTER The ECD Model X80 Universal Transmitter is a single- or dual-channel transmitter designed for the continuous measurement of pH, ORP, pION, dissolved oxygen, turbidity, conductivity or resistivity in a general-purpose industrial environment. The transmitter digitally communicates with any ECD Model S88 or S80 Intelligent Sensor, automatically configuring the transmitter’s menus and display screens to the measured parameter. The same transmitter can be used for any of the measurements; eg, plug an S88 Conductivity Sensor into a Model X80 pH transmitter and it will automatically reconfigure into a conductivity transmitter. There is no longer any need to inventory multiple instrument types, as the one transmitter will automatically configure to any of the listed measurements.
