Hello guys. Just want to do a verification with our heating oven range is up to 150?C. I have here a digital thermometer, but I want to know if what type of thermocouple should i use during the verification, I need some 3 meters long thermocouple. Although I do have 1 meter long of type J and K but I have doubts in using it because I dont know there application type, I am afraid that the thermocouple will bend or deformed when I close the door of the oven. please need some advise. thank you.
