About thermometers and pyrometers; liquid filled, for direct reading, not combined with other instruments

HS code 902511 covers thermometers and pyrometers that are liquid-filled and designed for direct reading, without being combined with other instruments. These devices play a crucial role in a wide range of industries, from manufacturing and healthcare to research and development. They are essential for accurately measuring and monitoring temperatures, enabling precise control and optimization of various processes that are temperature-dependent.

Production process

The production of thermometers and pyrometers under HS code 902511 typically involves several key steps. First, the liquid-filled sensor element is manufactured, often using specialized glass or metal alloys. This sensor is then integrated into a housing or casing, which may be made of materials such as plastic, metal, or a combination of both. The final assembly process includes calibration and testing to ensure the accuracy and reliability of the instrument.

Production inputs

The main inputs required for the production of thermometers and pyrometers under HS code 902511 include raw materials such as glass, metals (e.g., mercury, alcohol, or other liquids), and various plastics or metals for the housing and casing. Additionally, specialized manufacturing equipment, such as precision glass-blowing tools, calibration devices, and testing apparatus, are essential for the production process. Skilled technicians and engineers are also a critical input, responsible for the design, assembly, and quality control of these instruments.

Production outputs

The primary output of HS code 902511 is thermometers and pyrometers that are liquid-filled and designed for direct reading, without being combined with other instruments. These devices are widely used in a variety of industries, including 902580 Thermometers, pyrometers, etc. not combined with other instruments, 902610 Instruments and apparatus for measuring or checking the flow or level of liquids, and 902680 Instruments and apparatus for measuring or checking variables of liquids or gases, n.e.s..
