A number of pre-calibrated modules for humidity or humidity and temperature are available that can provide a variety of outputs including: frequency output, voltage output or digital output. Units can be provided pre-calibrated and temperature compensation is possible for some versions. Customized enclosures are also possible. A special environmental coating is available for harsh environments including salt air. We can also work with customers to provide special enclosures, packaging and mounting. All modules are ISO-9001 manufactured.

 
Model EE04
Appliance RH Sensor
The EEO4 was originally developed for the appliance industry (clothes dryers) and can be provided with a frequency or voltage output. It is available as a plug in board with or without a protective filtered assembly that can be easily installed in a manufactured product. Utilizes a passive temperature sensor. Versions of this product can be customized to required size and output. 0-100% RH, 3%RH, -40 to 185F (-40 to 85C).

Model EE03
Digital RH and T Module
The EE03 is a compact inexpensive, pre calibrated, plug-in module that is digitally communicating and fully temperature compensated from -40F to 185F (-40 to 80C). It's two wire digital protocol will travel up to 100 ft over a twisted pair. One unique feature of this module is that it can be used to measure surface humidity concentrations, which can be used to predict if dew point conditions are eminent. This product is deal for building and equipment monitoring including economizer and mold control for HVAC applications. With the digital signal delivered directly to a microprocessor, calculation of other humidity variables such as enthalpy, dew point, or humidity ratio can be easily and inexpensively calculated. (AirTest can also recommend micro based calculation algorithms you may want to utilize). 0-100% RH, 3%, -40 to 185F (-40 to 85C)

Model EE46
Surface Dew Point
The EE46 sensor specifically developed to detect surface humidity conditions and to provide a switched indication when surface humidity is approaching 90% RH, indicating that condensation is imminent. A large thermal mass built into the sensor ensures thermal equilibrium is achieved with whatever surface it is attached to. Often used to monitor condensation conditions for radiant cooling systems. Working Range: 10 to 100% RH, 0 to 122F (0 to 50C). NC/NO Relay for 24VAC, 1 Amp
