I was not sure how critical the connectors are for the thermocouple. Right now I just have if connected with a terminal block. Can I just use something like a plug and jack like for a microphone?
I agree with Dr.Al. You need the correct connectors for themocouples. They do not make special connectors for no good reason. Of course they'll work with other connectors but that will kill accuracy and that makes the whole point of measuring worthless.
