Application Note:

  • If necessary, please check out K type thermocouple extension wire with mini male plug.
  • There are 2 polarities for K type thermocouple: positive and negative. Please check polarity of K type thermocouple before use. Wrong polarity may cause temperature measuring error.
  • It is also easy to test the polarity of K type thermocouples. The negative wire is MORE magnetic than the positive wire. Just put a magnet up to each wire. One will be more magnetic than the other.
