Feature

Spesification

Temperature Sensor

Range: -20° to 70°C (-4° to 158°F)
Accuracy: ±0.21°C from 0° to 50°C (±0.38°F from 32° to 122°F)
Resolution: 0.024°C at 25°C (0.04°F at 77°F)
Response time: 6 minutes in air moving 1 m/s (2.2 mph)
Drift: <0.1°C (0.18°F) per year

RH Sensor

Range: 1% to 100% RH at -40° to 75°C (-40° to 167°F), non-condensing; exposure to conditions below -20°C (-4°F) or above 95% RH may temporarily increase the maximum RH sensor error by an additional 1%
