Bacterial Filtration Efficiency Tester Model:FTech-0469 Standard:YY0469-2004,YY/T 0969-2013,ASTMF2100,ASTMF2101,EN14683 ect. Features 1.1,Standard test cabinet, touch screen + PLC systemis easy to operate. 1.2,The sampler is Anderson level 6 sampler. 1.3,The chamber is made of quartz glass with a length of 600mm and a diameter of 80mm 1.4,The sprayer is made of quartz glass which is corrosion-resistant. 1.5,The vacuum pump: pumping flow 57L/Min. 1.6,The test tube holder is made of stainless steel, durable, humanized design, easy to use; 1.7,Add fixed tooling on the base of the sampler to prevent the sampler from sliding 1.8,The test cabinet is equipped with exhaust device to keep the negative pressure all the time. 1.9,The door of the test chamber is equipped with large observation window and operation gloves, so as to observe during the test and operate the test. Exhaust System 2.1,It is composed of filter, axial flow fan, stainless steel smoke exhaust pipe, smoke hood and frequency converter; 2.2,The smoke exhaust pipe and hood are made of stainless steel, extending the service life 2.3,The smoke exhaust air speed is controlled by PLC + frequency converter to realize stepless adjustment of air speed 2.4,The frequency converter is Taiwan delta frequency converter, which makes the wind speed regulation more convenient and accurate; 2.5,Equipped with the micro differential pressure sensor imported from the United States, measuring range: 0 ~ 500pa, accuracy: ± 1.0% FS; hysteresis: ± 0.1% FS; non repeatability ± 0.05% FS; Spray system 4.1,It includes oil-water separator, mass flow controller, peristaltic pump and sprayer. 4.2,Oil water separator: separate water vapor in compressed air; 4.3,Mass flow controller: control jet flow, flow accuracy 2%; 4.4,Peristaltic pump: control spray flow 4.5,Sprayer: spray device. Sampling system 4.1,The range of micro differential pressure sensor imported from the United States: 0 ~ 5000Pa, accuracy: ± 1.0% FS; hysteresis: ± 0.1% FS; non repeatability ± 0.05% FS, constantly monitoring the air mist chamber and sampling pressure; 4.2,Mass flow controller: control the pumping flow of vacuum pump, flow accuracy 2%; 4.3,The vacuum pump: pumping flow 57L/Min. 4.4,The filter filters the sampling system twice to make the test result more accurate. Operation syatem 5.1,Touch screen + PLC control system, friendly interface, easy to operate. 5.2,The spray flow can be automatically set and fed back on the touch screen to achieve automatic control. 5.3,The spray flow of peristaltic pump can be set automatically on the touch screen, and the flow can be calibrated to make the spray flow more accurate; 5.4,The sampling flow can be automatically set and fed back on the touch screen to achieve accurate flow control 5.5,During the signal acquisition and processing module, data such as pressure in the box, pressure of the spray chamber, spray flow, sampling flow and sampling pressure were collected and displayed in real time. 5.6,If the data is abnormal during the test, the software will automatically pop up the data abnormal alarm information and automatically record it for easy viewing 5.7,Test data can be set by parameter setting,test datecan be saved ,viewed and exported; 5.8,Touch screen operation software, friendly interface, powerful data interaction function, more suitable for scientific research and analysis; 5.9,Cleaning function: one button operation, and pop up the corresponding prompt dialog box, simple and convenient
