The EMD-4000 is capable of withstanding

environments where organic vapors are present. It

recovers from condensing environments and may

be used at temperatures up to 185°F (85°C). The

EMD-4000 is also capable of in situ measurement of

soluble water in organic liquids such as transformer

oil, gasoline, toluene, acetone, and other

compounds of varying hydrogen bond strengths.

The EMD-4000 is highly repeatable and

interchangeable. The sensor is manufactured in

high yields to ±5% RH or better tolerances. This

results in a sensor that can be used in many

designs without the need for humidity calibration,

where the measuring circuit can be calibrated with

external reference resistors. The EMD-4000 exhibits

function of humidity and temperature and has low

hysteresis and fast response.

The EMD-4000 is priced for Original Equipment

Manufacturers (OEMs) with requirements to incorporate

humidity sensors in HVAC controls, data loggers,

appliances, automotive applications and consumer

products.
