There are two accuracy specifications listed for the SI-111SS:
- One for when the difference in the target and sensor body temperatures is less than 20°C (more accurate)
- One for when the difference in the target and sensor body temperatures is greater than 20°C (less accurate)
Using a radiation shield with the sensor helps keep the sensor body temperature in close approximation to the ambient air temperature. Ultimately, the need to protect the sensor from short-wave radiation is dependent on what is being measured and under what conditions. For example, Campbell Scientific recommends using a radiation shield for canopy measurements.
