What measurements does this data logger support?

The UX100-023 data logger supports the following measurements: Relative Humidity and Temperature


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)
