Oxygen Detectors
There are three types of oxygen detectors available: a non-explosion proof partial pressure type, a non-explosion
proof capillary type with a replaceable sensor, and an explosion proof (CSA) capillary type with a replaceable
sensor. The capillary type’s output is less susceptible to variations in atmospheric pressure than the partial
pressure type. The CSA type oxygen detector (65-2514RK) and the non-explosion proof capillary type detector
(65-2494RK) has a replaceable plug-in sensor inside the detector housing. The entire oxygen detector must be
removed if replacement is required for the 65-2510RK.
The table below outlines the M2A part numbers and replacement detector part numbers for the oxygen detectors.
