Environmental Conditions |
Like all relative humidity sensors, when
exposed to contaminants and/or extreme environmental
conditions, accuracy degradation could result. For
maximum long term stability, sensor should not be
exposed or subjected to organic solvents, corrosive
agents (strong acids, SO2, H2SO4, Cl2, HCl, H2S, etc.),
and strong bases (compounds with PH greater than 7).
Dust settling on the sensor surface will not affect
sensor performance except possibly to decrease the speed
of response |
|
Range |
0 to 95% RH (non-condensing) |
