Product principle:

Consisting of an aerosol generation system, an aerosol chamber and aerosol transport device, a negative pressure cabinet, a 28.3L/min sampler, etc., the entire detector is uniformly controlled by a control console. The control console adopts a microcomputer control system to coordinate and control the work of the aerosol generation system, transmission system, negative pressure cabinet, and sampling system, and displays the working status in real time. The entire measurement work is automatically completed.

Technical features:

1. Negative pressure experimental system to ensure the safety of operators;

2. The negative pressure cabinet is equipped with a peristaltic pump, with six stage Andersen for both A and B circuits;

3. The flow rate of the peristaltic pump can be set;

4. The flow rate of the special microbial aerosol generator at night can be set, and the atomization effect is good;

5. Embedded high-speed industrial microcomputer control;

6.10.4 inch industrial grade high brightness color touch screen;

7. USB interface, supporting USB data transfer and storage;

8. The cabinet is equipped with high brightness lighting;

9. The inner layer of the cabinet is made of stainless steel and processed as a whole. The outer layer is sprayed with cold rolled sheet, and the insulation and flame retardant properties between the inner and outer layers are maintained;

10. Detachable bracket, adjustable in height, supports and moves dual-purpose casters.
