    Application Notes
    • 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.
    • Chromel/Alumel is vulnerable to sulfidic corrosion which can result in a thermocouple failure. Apply a thin layer of Zirconia coating will protect the TC from corrosion and thus extend its service life. Re-apply the coating if there is a sign of layer flaking/peeling after the process.
