Virtually all EE humidity products are available with an optional durable coating
that protects the sensor and associated electronics in extremely dirty, wet, or corrosive environments. This coating, initially developed
for humidity measurement application in industrial, automotive and marine applications preserves sensor life and long term stability in
the most challenging environments. It allows the free transmission of water vapor yet rejects liquids and harsh vapors.
The coating will also allow the sensor to operate in very wet environments or to be periodically immersed in water without affecting sensor
response or accuracy. When this coating is applied, RH sensor response is reduced from T90 = 6 seconds to T90 = 30 seconds.
The coating has proven itself over years of operation in salt air and salty fog, wood drying kilns, cheese production, and in dirty,
dusty and very corrosive environments. Please contact AirTest for further details.
