  • Accuracy: ±3.0% RH (20–80% range); ±4.0% RH for other values

• Ambient Temperature

  • Range: –20.0 °C to 60.0 °C (–4.0 °F to 140.0 °F)

  • Resolution: 0.1 °C (1 °F)

  • Accuracy: ±1.5 °C (0–45 °C); ±1.5 °C beyond that range—or ±2.0 °F (32–113 °F) and ±3.0 °F outside

• Wet Bulb Temperature

  • Range: –20.0 °C to 60.0 °C

  • Resolution: 0.1 °C

  • Accuracy: ±1.0 °C (0–45 °C); ±1.5 °C outside (equivalent °F ranges apply)

• Dew Point Temperature

  • Range: –50.0 °C to 60.0 °C (–58.0 °F to 140.0 °F)

  • Resolution: 0.1 °C (1 °F)

  • Accuracy: ±1.0 °C (32–113 °F); ±1.5 °C beyond

All measurements are updated at a rapid sampling rate of 2.5 readings per second, offering near real-time insights into changing conditions.

User-Friendly Features for Enhanced Usability
