A gas monitoring device for monitoring gas levels within a chamber is provided.
The gas monitoring device includes a housing having a probe with a sensor disposed
on the probe. The probe extends through the housing and into a chamber such that
the sensor is within the chamber. The housing includes a first passageway disposed
about the probe and second passageway disposed about the first passageway. During
operation of the gas monitoring device, a temperature adjusting medium enters the
second passageway through an inlet of the housing and then enters into the first
passageway via the second passageway. As the temperature adjusting medium travels
through the first passageway, the temperature adjusting medium adjusts the temperature
of the probe. The temperature adjusting medium adjusts the temperature of the probe
through thermal conduction. As the temperature of the probe adjusts, the temperature
of the sensor also adjusts through thermal conduction.
