Product review (1 stars): Inferior J U N K
DO NOT buy these. In order for a plug and jack to work, they MUST be made of Chromel and Alumel just like the thermocouple wire otherwise, because you now are connecting to dissimilar metals you are creating t-couple junctions at each connector!! Use these and you CAN and WILL significantly change your readings simply by raising or lowering the temp of the JACK AND PLUG!!! EACH SET becomes a T-couple!!! THEY ABSOLUTELY WILL CAUSE FALSE READINGS!
