Condition:100% Brand New Item Type: Handheld Thermocouple Index Number: K Operating temperature: 0-800 degrees Celsius (long-term), 0-1100 degrees Celsius (short-term) Material: 304 Stainless Steel Probe Diameter: Approx. 3mm/0.1in Probe Length: Approx.100mm/3.9in Measurement Object: Copper, tin, aluminum, furnace, etc. Application Range: Widely used in petroleum, chemical industry, machinery, metallurgy, textile, food, aerospace chemical industry, etc. Working Principle: The electrode of the armored thermocouple is composed of two different conductor materials. When there is a temperature difference between the measuring terminal and the reference terminal, a thermoelectric potential will be generated, and the working instrument will display the temperature value corresponding to the thermoelectric potential. Overview: Armored thermocouples and thermal resistances have the advantages of bending, high pressure resistance, fast thermal response time and sturdiness. They are the same as assembled thermocouples and thermal resistances. They are used as sensors for measuring temperature, usually with display instruments, The recorder is used in conjunction with the controller, and can also be used as a temperature sensing element for assembled thermocouples and thermal resistances. It can directly measure the temperature of liquid, steam and gas medium and solid surface in the range of 0C ~ 1100C (thermocouple), -200 ~ 500C (thermal resistance) in various production processes. Armored thermocouples are the same as general industrial thermocouples, and are matched with display instruments. They can automatically detect or adjust the surface temperature of gas, liquid medium or solid within a certain range.
