  • 125 x 92 x 31 mm (4.9 x 3.6 x 1.2 inches)
  • 170 g (6.0 oz) with batteries

Internal 12-Bit Temperature Sensor

  • Measurement range: -20°C to 50°C (-4°F to 122°F)
  • Accuracy: ±0.21°C from 0° to 50°C (±0.38°F from 32° to 122°F); ±0.13°C (0.24°F) typical

  • Accuracy Drift: <2% over 5 years typical
  • Hysteresis: 1% typical

External Sensors

  • For External Sensor Specifications, see the sensor's user manual.

Battery Life

  • The batteries will last one year in typical conditions (logging intervals of ≥ 1 minute with weekly offloads and average temperatures greater than 10°C or 50°F). Frequent offloads and/or extreme temperatures will reduce battery life.
  • At temperatures below freezing (0°C or 32°F), batteries will typically require replacement every six months. In these conditions the battery level bar graph should be checked regularly.
