Handle thermocouple also known as handheld thermocouple for measuring the surface temperature of various shapes of solid media as well as measuring the temperature of liquids and gases. Handle thermocouple has a wide range of use, is not limited by the shape of the surface of the object, lightweight appearance, easy to carry, because the handle thermocouple has a small diameter, flexible, anti-vibration, fast thermal response time and fastening durable, high reliability, The product and digital display instrument can be used to directly measure and display the temperature of various media in the range of 0~1200℃ in different production processes, is widely used in metallurgy, chemical industry, textile, printing and dyeing, paper making, rubber, plastic, ceramics, granary and other industrial departments, enterprises.

Model and specification

Thermal response time of handle thermocouple: when there is a step change in temperature, the time required for the output change of thermocouple to equal to 50% of the step change is called thermal response time, expressed by τ0.5. The thermal response time is not greater than the following table:
