
The thermocouple and humidity sensor
will start aging under the influence of
oxidation, reduction, corrosion, pollution,
vaporization, diffusion or other
metallurgy. The aging process will affect
its precision seriously.

Cleaning and inspection of temperature
probe:
The smoke, coal, dust, grease attached
on the protective tube of temperature
probe will slow down the heat conduction
of the thermocouple and cause
measuring error. Therefore, it should be
cleaned periodically. The metal coating
of thin thermocouple should be replaced
properly upon the occurrence of
corrosion.

Cleaning and inspection of humidity
sensor:
The smoke and dust attached on the
humidity sensor will slow down the
function of humidity sensor and cause
measuring error. Therefore, it should be
