I have to do high temp testing inside a shipping container. Do I need to run 1 continuous thermocouple to the meter or could I run a high temp wire inside the container and connect it up to a regular thermocouple wire from there to the meter?

Asked by: Segan11
Thank you for your inquiry Segan11. Either or would work but we recommend you use a wire that is rated for the temperature inside the container.

What is IEC standard

Asked by: J R W
Thank you for your interest in our Product . IEC will apply to the color coding of the jacket and insulation only. For Thermocouple Grade Type J for example, the color coding is a Black jacket with a (+) Black and (-) white insulation All accuracy testing of the wire is conducted in accordance with ASTM E 230 which has slightly tighter tolerances in the lower temperature ranges than the IEC 584 specification.

Does this come with the connectors to attach to the meter?

Asked by: laz87
Thank you for your inquiry laz87. No, this wire does not come with the connectors. The connectors are sold separately.
