HIH-4000 Series

Humidity Sensors

The HIH-4000 Series Humidity Sensors are designed

production calibration costs. Individual sensor calibration data

is available.

The HIH-4000 Series delivers instrumentation-quality RH

(Relative Humidity) sensing performance in a competitively

two lead spacing configurations, the RH sensor is a laser

multilayer construction provides excellent resistance to most

application hazards such as wetting, dust, dirt, oils and

• Low power design

• High accuracy
