Hobo UX 100 ExtTemperature/RH

Temperature Sensor

Range: -20 to 70C (-4 to 158F)
Accuracy: 0.21C from 0 to 50C (0.38F from 32 to 122F)
Resolution: 0.024C at 25C (0.04F at 77F)
Response time: 6 minutes in air moving 1 m/s (2.2 mph)
Drift: 0 .1C (0.18F) per year



RH Sensor

Range: 1% to 100% RH at -40 to 75C (-40 to 167F), non-condensing; exposure to conditions below -20C (-4F) or above 95% RH may temporarily increase the maximum RH sensor error by an additional 1%
Accuracy:2.5% from 10% to 90% RH typical to a maximum of 3.5% including hysteresis at 25C (77F); below 10% and above 90% 5% typical
Resolution: 0.05%
Response time: 5 minutes to 90% in airflow of 1 m/s (2.2 mph)
Drift: 1 % per year typical
Cable length: 1.83 m (6 ft)
