Expendable thermocouple tips(type B,R,S)

Expendable thermocouple tips(Type B,R,S) Thermocouple tip/head are used for measurement of molten metal temperatures.  Thermocouple tip has two type. Type:QR-KW/S/R/B-602J     Type:QR-KW/S/R/B-604J ( The letter J stand for the exact thermocoupl wire and the tolerance is no more than 2°c). Thermocouple wire: Thermocouple tip:   

Type	Model	Max.Temperature
Type WRe(W25%Re-W3%Re)	QR-KW-602/604	1820°c
Type    S    ( Pt-Pt10%Rh)	QR-KS-602/604	1760°c
Type    R    (Pt-Pt13%Rh)	QR-KR-602/604	1760°c
Type    B    (Pt6%Rh-Pt30%Rh)	QR-KB-602/604	1800°c

We have two type of thermocouople tips,the shape of tip bottom is round,which we called type 602 thermocouple tip.The other shape of tip bottom is triangle,which we called type 604. According to the different way of connection,thermocouple connector has two types are 602 connector and 604 connector. This is 602 thermocouple tip and 602 connector    This is 604 thermocouple type and 604 connector  Advantages:  (1)high accuracy,rapid reaction,reliablity and stablility.  (2)Excellent precision with 5c for the tolerance.  (3)Reaction time quikly,reaction time≤5s.  (4)High temperature limit,hight temperature:1800degrees celsius.
