Description
Typically used to protect a direct immersion style probe such as the Burns “A” style for air or water temperature measurements. The PVC plastic version works well as a sun shield to minimize radiation heating of the temperature sensor.
Guard tube thermowells providing protection from solar and physical damage in a variety of configurations.
