Model 485 Digital Hygrometer - 0 To 100% Relative Humidity Range | Dual 4.5 Digit Lcd Display, Hold Key Function, 25 Reading Memory

Model 485 Digital Hygrometer is a versatile,compact,hand-held instrument for measuring percentage of relative humidity and temperature in A F or A C.Dew point and wet bulb temperature is derived from relative humidity and temperature measurements and displayed on the 0.4 ? LCD 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 a ideal for technicians needing to take multiple readings for later analysis.
