Needle Thermocouple
(#CNS) Ecklund Needle Thermocouples are specially designed for conducting heat penetration tests of foods in cans, jars, and plastic packages. The non-projecting connector type thermocouples combine convenience and accuracy. Also, they permit test containers to be filled and closed in the same manner as the commercial pack. Needle Thermocouples are Type-T with a 1/16" (1.6 mm) diameter tubular stainless steel body. A needle thermocouple installs into a Thermocouple Receptacle. When purchased, a needle thermocouple comes with a Thermocouple Gasket installed.
Determining Thermocouple Length
The length of an Ecklund Needle Thermocouple depends on the size of the container you will be testing. For cans, plastic cups, and recart packages, the thermocouple should be sized to reach the middle of the container. For glass jars, the thermocouple should be sized so the tip is at the cold spot of the container.
