Digital Hygrometer -Series 485-1
Measures % RH and Temperature
Model 485-1 Digital Hygrometer is a versatile, hand-held instrument for measuring percentage of relative humidity and temperature in °F or °C. Dew point and wet bulb temperature is derived from relative humidity and temperature measurements and displayed on the 0.4" LCD. A display Hold key freezes the current temperature and relative humidity readings for situations where readings fluctuate. Store up to 25 readings with the non-volatile memory function-ideal for technicians needing to take multiple readings for later analysis.
