ABSTRACT:
An in-situ, thermocouple, soil hygrometer or psychrometer probe equipped with a removable, moisture pervious thermocouple shield, so that the thermocouple may be periodically cleaned for increased life and improved performance, has an elastic, protective boot that retains the shield in place about the thermocouple and permits easy removal of such shield. The boot is made of low-vapor sink material, so as not to interfere with proper operation of the thermocouple, and is configured to firmly grip the thermocouple mount, so that pulling of the thermocouple from its lead wires during removal and replacement of the shield is avoided.
