The 7773 can be configured to suit diverse needs. For flow applications, it is configured to act as a sample flow chamber. Once installed in process pipework the electrodes can be easily removed for maintenance and calibration without having to uninstall the flow chamber part of the housing. In immersion applications the 7773 unit can be easily connected to an immersion pipe by the ¾-inch NPT female connector on top of the housing.
Preamplifier options allow interface with Honeywell or other pH instrumentation. The preamplifier circuitry is sealed against moisture and electrically shielded by its metal enclosure. The internal preamplifier enables the pH signal to be sent over ordinary unshielded wire in excess of 305 m (1,000 ft.) to the measuring instrument.
