The ZHCY-07 quantitative sampling robot is a high-precision automated equipment designed specifically for hygiene testing of central air conditioning and ventilation systems. It integrates advanced sensing technology, intelligent control, and precision machinery, and is widely used in fields such as disease control centers, third-party testing institutions, and health supervision departments. Its core characteristics are reflected in the following aspects:

　　1、 High precision sampling and compliance design

The robot strictly follows national standards such as WS394-2012 and WS/T395-2012, and adopts a dual-mode sampling method of scraping and wiping. The sampling area is accurate to 50cm2, the sampling error is less than 5%, and the relative deviation is controlled within 3%. The closed sampler is designed with an airflow return duct and manufactured using photopolymerization 3D printing technology, effectively avoiding secondary pollution and ensuring the reliability and compliance of sampling data.

　　2、 Intelligent control and full automation

The device is equipped with a full computer software operating system, which can be wirelessly controlled through a laptop and supports remote video monitoring and real-time operation. Users can intuitively set the sampling program through the interface, achieving one click automatic sampling (including dust collection and microbial sampling) without manual intervention. Its intelligent control system also has blind spot free visual navigation: the front 3-megapixel pan tilt camera (180 ° vertical rotation/360 ° horizontal rotation) works in conjunction with the rear camera, and with adjustable LED lighting, achieves 360 ° comprehensive monitoring inside the pipeline.

　　3、 Flexible adaptability and strong obstacle crossing ability

The robot adopts a lightweight aluminum alloy body, weighing only 4-6kg, with a small size that can enter rectangular ducts with a minimum size of 100 × 160mm. Equipped with a German imported motor-driven track system, the obstacle crossing height exceeds 7cm, the climbing angle is greater than 45 °, and it can even achieve 360 ° in-situ rotation in complex pipeline environments. Its wireless design breaks free from cable constraints, supports distance free operation, and significantly improves detection efficiency.

　　4、 Long lasting endurance and durability

Built in 4400mAh large capacity lithium battery, supporting continuous operation for 8 hours, with a charging time of only 4 hours. The fuselage is made of aviation aluminum alloy material, with a surface treated by oxidation sandblasting, which increases hardness and corrosion resistance by more than 30%. It is also easy to disinfect and suitable for frequent use in harsh environments.

　　5、 Multi scenario applications and data management

In addition to air conditioning system testing, robots are also suitable for hygiene monitoring in public places such as hospitals, shopping malls, and transportation hubs. Its software system can automatically generate sampling reports and data analysis charts, support remote networked data transmission, and provide complete basis for health evaluation and supervision.

Conclusion

The ZHCY-07 quantitative sampling robot redefines the efficiency and reliability of environmental detection through the integration of high-precision sampling, intelligent control, strong power, and long-term endurance. It not only reduces manual operation errors, but also becomes a crucial technical equipment in the field of modern public health monitoring with the advantages of compliance, adaptability, and automation.
