Handheld flat surface thermocouple selects φ5～φ8 armored thermocouple, probe tip with a raised cylinder, to limit the distance between tested objects and ribbon temperature element, to prevent damage of temperature testing component. With a straight-held large handles , which has spring-soft handle at the end, the lead wire is connected to the portable digital tachometer display’s flat yellow plug, easy for connection of secondary meters. The testing length is according to users’ need, applied to the measurement of casting, molding, bearing, glassware and other stationary objects surface temperature

The distance between components and insulation resistor is not less than 20M (500V Ω DC ).

Continuous measurement time : in 400C above , the continuous use of 1 minute. 

Graduation:  K, E

1) Variety, measuring range and tolerance

2) handle the form of size and insert depth
