Electronic Relative Humidity (RH) Indicator

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.
