Product Description:

WRNK-181 and WREK-181 hand-held thermocouples, also known as handle thermocouples, are specially designed for measuring the surface temperature of various solid media and measuring the temperature of liquids and gases. The handheld thermocouple has a wide range of applications. It is not restricted by the shape of the object surface. It is lightweight and easy to carry. Because the handheld thermocouple has the advantages of small diameter, bending, vibration resistance, fast response time, fastness and durability, and high reliability, the product can directly measure and display various media in the range of 0~1300 C in different production processes. The temperature is widely used in metallurgy, chemical industry, textile, printing and dyeing, paper making, rubber, plastics, ceramics, granaries and other industrial sectors and enterprises.

Two, model specification:

1) no temperature range and material of the protective tube are specified, and the material of the protective tube shall be supplied by 1Cr18Ni9Ti.

2) the final figure of the shell type insulated product is the same as that of the insulated product, for example, the shell type is WRNK-182/WRNK-188.

Three, thermal response time:

When the temperature changes step by step, the time required for the thermocouple output to change to 50% of the step change is called thermal response time. It is expressed by tau 0.5.
The thermal response time of hand thermocouple is not greater than that of the following table:
