Hazardous Area Oxymitter DR
The Hazardous Area Oxymitter DR meas- ures net oxygen concentration in the pres- ence of all the products of combustion, including water vapor. Therefore, it may be considered an analysis on a “wet” basis. In comparison with older methods, such as the portable apparatus, which provides an analysis on a “dry” gas basis, the “wet” analysis will, in general, indicate a lower per- centage of oxygen. The difference will be proportional to the water content of the sam- pled gas stream.
c.System Configuration
Hazardous Area Oxymitter DR units are available in three length options, giving the user the flexibility to use an in situ penetra- tion appropriate to the size of the stack or duct. The options on length are 457 mm (18 in.), 0.91 m (3 ft), 1.83 m (6 ft).

Abrasive shields are offered for applications where abrasive particulates are present. Acid resistant cells are available for SO2 and HCl environments. Bypass and probe mounting jacket options are available for process temperatures above 1300°F (705°C).
d.System Features
1.The cell output voltage and sensitivity increase as the oxygen concentration decreases.
2.Field replaceable cell, heater, thermo- couple, and diffusion element.
3.The Hazardous Area Oxymitter DR is constructed of rugged 316L stainless steel for all wetted parts.
