Function: 1. It is resistant to high voltage, has a fast thermal response time, and is durable. 2. It can directly measure the temperature of copper/tin/aluminum and other liquid, steam, and gas media, as well as solid surface temperatures from 0°C to 1100°C (short-term measurement) in various production processes. 3. The thermocouple has a simple structure, is easy to use, highly accurate, and has a long service life. 4. It features a handheld design, small in size, making it convenient to use and carry. 5. Made of stainless steel, it is not prone to corrosion or rust and can be used for a long time. Specification: 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, oven, etc. Scope of Application: Widely used in petroleum, chemical industry, machinery, metallurgy, textiles, food, aerospace chemical industry, etc. Working Principle: The electrode of the armored thermocouple consists of two different conductor materials. When there is a temperature difference between the measuring terminal and the reference terminal, a thermoelectric potential is generated, and the working instrument displays the temperature value corresponding to the thermoelectric potential. Overview: Armored thermocouples and thermal resistors have the advantages of flexibility, high pressure resistance, fast thermal response time, and robustness. They are similar to sheathed thermocouples and thermal resistors. They are used as sensors to measure temperature, typically with display instruments, recorders, and controllers. They can also serve as temperature sensing elements for sheathed thermocouples and thermal resistors. They can directly measure the temperature of liquid, steam, and gas media, as well as solid surfaces, within the range of 0°C ~ 1100°C (thermocouple) and -200 ~ 500°C (thermal resistor) in various production processes. Armored thermocouples, like general industrial thermocouples, are matched with display instruments. They can automatically detect or adjust the surface temperature of gas, liquid media, or solids within a specific range. Package List: 1 x Thermocouple
