EN14683 Mask Bacteria Filtration Efficiency（ BFE ）Tester With PLC , Lab View Control

EN14683 Mask Bacteria Filtration Efficiency( BFE )Tester with PLC , LabView Control

Product Overview:

Bacteria filter efficiency [BFE] tester is developed based on the international advanced design concept of similar equipment, based on YY 0469-2011, YY / T 0969-2013 and other standards. It is mainly used for metrology verification departments, scientific research institutes, medical Mask production unit and its related testing department test the performance of mask bacterial filtration efficiency. It has the characteristics of fast and accurate measurement of the bacterial filtration efficiency [BFE] of the mask. It is equipped with a bioaerosol generator and two Anderson 6-level samplers, which meet the requirements of ASTM F2100, ASTM F2101, EN14683 and other standards.

Mask Bacteria Filtration Efficiency [BFE] The tester adopts advanced technology and industrial computer control. The design friendly user interface and operation method make the user test simplified and easy to operate. The test results are displayed directly and are convenient and intuitive.

Features:

• The Mask bacterial filtration efficiency detector uses a negative pressure test system to ensure the safety of the operator;
• Measurement system, built-in liquid supply system, equipped with I, II two-level 6-level Anderson sampling system;
• The flow rate of the peristaltic pump can be set according to specific conditions;
• The microbial aerosol generator bacterial liquid mist flow size can be adjusted and set, and the atomization effect is good;
• Control system adopts PLC + LabView control, high-intensity color touch screen 10 inches, USB interface, supports U disk data transfer;
• Built-in high-brightness lighting lamp, convenient for observation;
• All flow control adopts mass flow control system;
• Front glass door is convenient for the operator to observe the experiment process;

Standards:

• YY0469 Mask bacterial filtration efficiency [BFE] detection standard
• YY / T 0969-2013 Standard for disposable medical masks
• ASTM F2100 medical mask material performance specifications
• ASTM F2101 Standard evaluation method for evaluating the bacterial filtration efficiency of medical mask materials using the bioaerosol of staphylococcus aureus;

Product Principle:

By aerosol generating system, aerosol chamber and aerosol transmission device, negative pressure cabinet, 28.3L / min

Sampler, etc., the entire detector is controlled by the console. The console uses 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.
