GAS SENSOR ACCESSORIES
Sensor Element Shield
The Sensor Element Shield can be screwed on to the
end of the gas sensor to help protect the sensor from
rain, dust, hose directed water, and debris floating in
the air. It can be installed on the Standard, Harsh and
Extreme gas sensors. The shield may slow response
time slightly depending on the surrounding air flow
conditions. Shield, p/n 31-1002.

Quick Disconnect Plug Kit
The Quick Disconnect Plug Kit can be added to the gas
sensor to provide a means of easily removing the gas
sensor for recalibration. This feature comes in handy
for gas sensors installed in blast cells, low temperature
rooms and hard-to-reach places. The gas sensor
cable can be quickly disconnected and the entire gas
sensor removed or replaced with a bench recalibrated
gas sensor. The gas sensor can then be brought to an
alternate location for recalibration or sensing element
replacement. Quick Disconnect Plug Kit, p/n 31-1001.
Option only available for field installation. Supplied
cable is 2 feet (0.6 meters) in length.
