Hi,
I am wondering about the range and accuracy of the k type (chromel/alumel) thermocouples. In some reference it -270 C to 1372 C.
But I guess it the range and accuracy is also limited by the device/reader electronics. Is it also limited by the type of wire used ? I have found some thermocouple with plug that can be connected to the device/reader and they come with different range which I don't understand but I get an impression that in addition to the limitation put by the device/reader electronics, the limitation also come with the type and maybe length of the wire. Am I understanding it correct ?
