 Event logging mode (1 second record) 128K bytes of data memory.
Languages
 English, French, Spanish, Italian, German
Sensors
 Dry Bulb Sensor- 1000 Ohm Platinum RTD
o Accuracy and Ranges: ±0.5 from 0°C to 120°C (±0.9°F from 32°F to 248°F)
 Waterless Wet Bulb (Humidity) Sensor
o Accuracy and Ranges: Expanded measurement uncertainty of 1.1°C (k=2)
between 0°C and 80°C (32°F and 176°F)
 Globe Sensor- 1000 Ohm Platinum RTD
o Accuracy and Ranges: ±0.5 from 0°C to 120°C (±0.9°F from 32°F to 248°F)
 Relative Humidity Sensor - Integrated circuit with capacitive polymer sensor
o Accuracy and Ranges: ±5% from 20 to 95% (non-condensing)
Operating Temperature Range
 Sensor Assembly: -5C to +100C
 Electronics: -5C to 60C
Housing
 Designed water resistant to a light rain or mist. If rain is frequent, best practice would be
to remote the sensor bar and keep the instrument sheltered.
