Sheathed thermocouple

⑴ It is usually used measure the temperature of the metal surface of the pipelines.The extraction tube is equipped with anti-vibration tight-top structure to ensure the elements close contact with the measured face when measuring.
⑵ The height 〃H〃of the extraction tube, the length 〃L〃 of sheathed thermocouple and the dimension of the extension lead wire 〃S〃shall be determined by users1 need.
