China Particle Protection Effect Detector of Mask

mask particle protection effect detector is to install the national standard head mold in the 500L self-cleaning detection cabin, wear the mask to be inspected on the head mold, and pass the mass median diameter of (0.6 ± 0.050) μm, the concentration occurs 20mg / m3 of saline aerosol and mass median diameter (0.3 ± 0.050) μm, oily aerosol with a concentration of 20mg / m3 are input into the self-cleaning detection chamber, the head model makes a sinusoidal curve to simulate breathing, using upstream and downstream photometric Take a sample and measure the concentration of salt aerosol and oil aerosol before and after the mask to evaluate the protective effect of the particulate matter of the mask. The mask to be tested can be worn on the national standard head mold to automatically detect the breathing resistance. It is suitable for the detection of the protective effect of particulate matter such as masks and filter materials by medical device inspection centers, disease prevention and control centers, hospitals, high-efficiency filter manufacturers, mask research and development and manufacturers.

Technical characteristics

The integrated design of the protective effect of the particulate matter of the mask and the detection of respiratory resistance, one machine for multiple purposes

Self-cleaning test cabin is equipped with operating gloves to facilitate the replacement of masks to be tested.

Three types of head mold compatibility design, plug and play, easy to replace.

The external saline and oily aerosol generator can be controlled to control the concentration of particulate matter.

Large touch display design, automatic display of respiratory flow curve and automatic calculation of particle protection effect.

The anti-leakage design of the whole particulate matter to protect the safety of laboratory personnel.

Photometer long-life laser light source, high-precision photomultiplier tube detection.

Photometer working time statistics, automatically prompt cleaning time.

The usage time of the HEPA filter is automatically counted, prompting to replace the HEPA filter.

Historical data can be exported via U disk or printed via embedded printer.
