Contact SupplierOn calm, clear nights leaf temperatures can drop well below air temperature. A radiation frost occurs when frost forms on the surface before the air temperature reaches freezing. The Apogee radiation frost dectector contains a high accuracy thermistor mounted in a rugged housing. The thermistor mimics a leaf, which provides estimates of leaf temperatures when monitoring radiation frost events
Â
Features: Thermistor accuracy is ± 0.1 C across a range of 0 to 70 C, providing accurate measurements at temperatures near zero where frost damage is likely to occur.
Output Options
Analog and digital output options include an unamplified voltage output or SDI-12 communication protocol.
Typical Applications
Applications include leaf temperature estimates in crop fields, orchards, and vineyards. Leaf temperatures returned by the detector can then be used to alert growers to the potential of frost damage to crops.
