The air purifier test chamber is the core equipment for evaluating the key performance of purifiers, such as clean air volume (CADR) and pollutant removal rate. The accuracy of its test results is directly related to product rating and market access. Among various influencing factors, the airtightness of the testing chamber is a fundamental condition for ensuring the reliability of experimental data. Once there is a leak, it will cause systematic deviation in the detection results.

As a combination of aerodynamics and cleaning technology, the performance of a vacuum cleaner directly depends on core parameters such as air flow rate, vacuum degree, suction power, and filtration efficiency. As a key tool for quantifying these indicators, vacuum cleaner air performance testing equipment provides scientific basis for product development and quality control through precise airflow control, pressure measurement, and data acquisition technology. Its core technical principles can be broken down into four major modules:

The horizontal and vertical combustion tester is the core equipment for evaluating the flame retardant performance of materials, and the accuracy of its test results directly affects the determination of the material's fire rating. To ensure the long-term stable operation of the instrument and meet standard requirements, calibration, daily maintenance, and troubleshooting are key steps.

As the core equipment for testing the flame retardancy of materials, the horizontal and vertical combustion tester is designed to integrate precision, safety, and intelligence, meeting the needs of multiple standard testing while improving operational efficiency and data reliability. Here are several core design highlights:

The horizontal and vertical combustion tester is the core equipment for evaluating the flame retardant performance of materials. By simulating the interaction between flames and materials, it accurately measures the flame propagation distance and combustion rate, providing key data support for material fire rating determination (such as UL94, GB2408 standards). The core of its technology lies in the quantitative analysis of flame dynamic behavior and combustion process.
