When the thermal imaging camera uses a 2× and 4× zoom, the measurement accuracy is ±2°C or ±2%, whichever is greater. (Tested at a distance of 5 m away from the black body at 25°C in a laboratory environment without wind)

When using 8× zoom or above, the temperature measurement accuracy is ±5°C (when using 8× zoom or above in the case of infrared cameras, the minimum focal distance is 35 m. The accuracy of temperature measurement at this distance is more likely to be affected by the environment, decreasing measurement accuracy.

Note: Due to differences in the emission rates of different black bodies and the effect of different environments on temperature measurement, the measurement results only represent the detection precision of the black body under the laboratory environment.
