3.3.4 The 33095 sensor housing

The ORBISPHERE 33095 sensor housing is also available for use with the GA2X00 sensor but
requires that the sample flow be turned off prior to insertion or removal of the sensor.
Sensor insertion is made by inserting the sensor into the housing and tightening the retaining collar
until it stops. Removal is made by unscrewing the collar and pulling the sensor out. Be sure that the
sample flow has been turned off before inserting or removing the sensor.
