The surface temperature of the solid medium handle type sheathed thermocouple measurement of various shapes and measurement of liquid and gas temperature. Handle type thermocouples using range is very wide, not subject to the restrictions of the shape of the object surface, beautiful appearance, light weight, easy to carry, because the handle type armoured thermocouple with small diameter, bending, anti vibration, thermal response time and firmness and durability, high reliability. The products and digital display instrument with the use of direct measurement and display of various production processes in 0~1200 DEG C within the scope of a variety of medium temperature, is widely used in metallurgical, chemical, textile, printing and dyeing, paper making, rubber, plastics, ceramics, granary, etc. industrial sectors and enterprises. The main technical parameters IEC584IEC1515GB/T16839-1997JB/T5582-91 characteristics of the thermal response time is less, reduce the dynamic error can be bent to bend the installation of high mechanical strength, high pressure performance
