Quite often, air temperature is not a reliable predictor of timing, duration and severity of frost events because plant canopy temperatures can be significantly different than air temperature under certain environmental conditions. On clear, calm nights, plant leaf and flower bud temperatures can drop below freezing even if air temperature remains above 0°C. This is called a radiation frost and is due to the lack of air mixing (wind) near the surface, and a negative net longwave radiation balance at the surface.
The detector comes with a 5 metre cable and a choice of analogue or SDI-12 outputs:
- SF-110-SS: Leaf Temperature Sensor, analogue output.
- SF-421-SS: Leaf Temperature Sensor, SDI-12 output.
