How to use Surface temperature thermocouple correctly?


  1. The Objective surface should be kept clean, as a result of oil, dust, or other insulating material. For example,  paint will affect the measurement accuracy .
  2. Measured surface should be flat, For example,  the measured object is rough or uneven, you need to use grease ,smear on its get better heat transmitting. Rough surface tends to cause the thermocouple sensor damaged or poor performance of  the accuracy .
  3. Measurement of surface area must be greater than the size of a probe sensor.
  4. Prohibit using surface thermocouple for rolling objects. Suggest to use scroll wheel temperature measurements Tecpel TPK-06 Rolling thermocouple to measuring rolling objectives.
  5. Take the vertical angle of 90 ° degrees.  The error should not exceed 5 ° degree angle to ensure the accuracy of temperature measurement
  6. 6. Do not measure the temperature exceeds its rated temperature, to avoid the thermocouple from being damaged.


    Does your TPK-02A, 02B or TPK-04L comply to the normal K type
    characteristic, between Temperature and electrimotive force ?
    Characteristic means a certain standard, such as ISO-xxxx ?
    Answer: All K type thermocouples from our company are made as per international standard ITS-90.
