7773 Flow and Immersion Mounting

​7773 mounting capabilities address the industrial measurements of pH and ORP in flo

w through or immersion applications. With seven housing configurations, the 7773 is available with the widest range of electrode, preamplifier, automatic temperature compensator and mounting assembly options.

The flexible wetted material choices include 316 stainless steel, glass-fiber reinforced polypropylene or Ryton making the assembly ideal for use in corrosive solutions at pressures up to 1034 kPa (150 psig) and temperatures up to 130°C (266°F).

​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.

​The 7773 mounting assembly facilitates accurate pH measurement resulting in efficient product quality and reagent control. In addition, features such as the long lifespan of Durafet II electrodes and the gel refill kit capability bring significant cost savings for the users.
