These sheathed thermocouple probes combine a straight handle with spring-protected leads and a connector for a portable temperature instrument. The large-grip WRNK-104 configuration offers K, E, J or T thermocouple selections. The slim-grip configuration offers K or J elements. Specify the required element, sheath material, diameter and insertion length together.
