2.5 Ordering information
The Model 5081 Two-Wire Transmitter is intended for the determination of pH/ORP,
conductivity (both contacting and toroidal), and for measurements using membrane-
covered amperometric sensors (oxygen, ozone, and chlorine). For free chlorine
measurements, which often require continuous pH correction, a second input for a pH
sensor is available. A hand-held infrared remote controller is required for local
configuration and calibration of the transmitter.
