5 Mechanical installation
5.1 General guidelines
Relative humidity is extremely dependent on temperature. Proper measurement of relative humidity requires
that the probe and its sensors be at exactly the temperature of the environment to be measured. Because of
this, the location where you choose to install the probe can have a significant effect on the performance of the
instrument. The following guidelines should guarantee good instrument performance:
a) Select a representative location: install the probe where humidity, temperature and pressure
conditions are representative of the environment to be measured.
b) Provide good air movement at the probe: air velocity of at least 200 ft/ minute (1 meter/second)
facilitates adaptation of the probe to changing temperature.
