Electronic Relative Humidity (RH) Indicator

01 February 2013

Brownell has introduced an Electronic Relative Humidity Indicator as an alternative to paper and chemical colour based indicators. 

The new Electronic Relative Humidity Indicator uses a polymer humidity sensor combined with a thermocouple to provide a digital display reading of relative humidity, ambient temperature and dewpoint. The operating range of the electronic relative humidity indicator is 5 to 80%RH, -20oC to +15oC dewpoint and -20oC to + 60oC temperature.

Traditional humidity indicator papers rely on a distinctive colour change usually from blue to pink to signify a dry to wet humidity change.  The electronic RH indicator removes the uncertainty associated with colour change indicators.
