HANNA HI 9564 Hand-Held Thermo-Hygrometers with Calibration

In addition to RH and temperature, HI 9565 will display the dew point with the press of a button. The dew point indicates the presence of water vapor in the air at a given temperature. With this feature HI 9565 permits useful and rapid environmental monitoring where a controlled microclimate is necessary, like greenhouses, museums, clean rooms and laboratories. Range RH 20.0 to 95.0% Range Temperature 0.0 to 60.0° C ( 32 to 140° F) Resolution RH 0.1% RH Resolution Temperature 0.1° C / 0.1° F Accuracy RH ± 3% RH ( 50 to 85% RH) ± 4% RH ( outside) Accuracy Temperature ± 0.5° C / ± 1° F Probe HI 70602 RH combined probe with built-in temperature sensor, microchip and 1 m ( 3.3' ) cable ( included) Battery Type / Life 1 x 9V / approx. 250 hours of continuous use; auto-off after 20 minutes of non-use Environment 0 to 60° C ( 32 to 140° F) ; RH max 98% non-condensing Dimensions 164 x 76 x 45 mm ( 6.5 x 3 x 1.8 " ) Weight 340 g ( 12 oz.) _ _ _ _ _ _ _ _
