AI Technical Summary
Existing gas sampling boxes have low accuracy, fixed and non-adjustable dimensions, and insufficient sealing, making them inconvenient to use, especially in field environments.
A multifunctional static box was designed, including a static box base, box body, top cover, and insulation mechanism. It adopts a threaded connection and rubber plug structure, and is equipped with temperature measuring holes, air sampling holes, and ventilation holes. It combines a foam layer and a tin foil layer to enhance sealing and insulation performance.
The gas sampling box has improved sealing and applicability, facilitated the handling and connection of the device, enhanced thermal insulation performance, adapted to different testing requirements, and improved the convenience of field use.
