Temperature Humidity Logger By Virtual Hydromet

This Temperature Humidity Logger measures air temperature and relative humidity. The internal temperature sensor is mounted on the circuit board inside enclosure of the datalogger case. Typically this sensor is left inside the case and measures ambient air temperature. Measurement range: Temperature: -40A to 123.8A C, RH: 0% to 100% RH AccuracyTemperature: better than +/- 0.5A C from 0A to 40A C see Plot A RH: A 2% from 10% to 90% over the range of 0A to 60A C, see Plot B; A 4% from 0% to 10% and 90% to 100% Resolution: Temperature: 0.01A C, RH: 0.03% Sample Rate: 1 minute to 24 hours, user selectable Drift: Temperature: 0.1A C/year, RH: <1% per year typical Response time in airflow of 1 m/s (2.2 mph) Temperature: 1 minute (max), RH: 1 minute(max) Time accuracy: Approximately A 1 minute per month Typical Operating range: Logging: -30A to 70A C (-4A to 158A F); 0 to 95% RH (non-condensing) Battery life: 1 year typical use Memory: 64K bytes
