Digital Hygrometer

( Dwyer )

Feature:
Model 485 Digital Hygrometer is a versatile, compact, hand-held instrument for measuringpercentage of relative humidity and temperature in °F or °C. Dew point and wetbulb temperature is derived from relative humidity and temperature measurements and displayed on the 0.4" LCD display. Hold key freezes the current temperature and relativehumidity readings for situations where readings fluctuate. Store up to 25 readingswith the non-volatile memory function – ideal for technicians needing to take multiple readings for later analysis.
