• Measuring range: From 0 to 30 m/s; from 0 to 5905 fpm
• Resolution: 0.01 m/s from 0 to 5 m/s; 0.1 m/s from 5 to 30 m/s; 0.1 fpm from 0 to 984.2 fpm; 1 fpm from 984.2 to 5905 fpm

Airflow**

• Measuring units: m3/h, m3/min, m3/s, cfm
• Measuring range: From 0 to 9999 m3/h, From 0 to 9999 m3/min, From 0 to 9999 m3/s, From 0 to 9999 cfm
• Resolution: 1 m3/h, 0.01 m3/min, 0.001 m3/s, 0.1 cfm

Temperature

• Measuring units: °C, °F
• Accuracy: ±0.5 °C, ±0.9 °F
• Measuring range: From -10 to +60 °C, from 14 to 140 °F
• Resolution: 0.1 °C, 0.1 °F

**Calculated value, only available on the app. Air flow is calculated with the surface given by the user. Accuracy of the result will depend on surface accuracy given by the user.
