The tester is designed to be compact and lightweight design, and during testing, just only the proper power supply and compressed air (anhydrous, no oil) is required to be used in laboratories, factories, etc. The Mask Particle Filtering Efficiency Tester is designed for suitable testing 20%-99.9% grade filter efficiency test, according to international standards to test the filter material. It is also suitable for the performance verification of research and development of new products, the quality control of production departments, third-party testing agencies, product performance verification laboratories, and quality and technical supervision departments for the determination of material properties.

Features:

The pneumatic clamp is equipped with a protection device, which is safe and convenient to use.

Equipped with glass rotor flowmeter, vacuum pump, laser dust particle counter.

Control system: The computer controls the test process, automatically collects data, and is equipped with dedicated computer and test software.

Aerosol generator: aerosols of salty particles and oily particles can be generated.

Equipped with aerosol particle electrostatic charge neutralization device.

Built-in filter efficiency test and mask loading test function, high detection efficiency and simple operation. The detection flow rate is automatically adjusted through the operation interface, and the control is accurate.

The computer automatically tests the gas concentration and automatically calculates the filtration efficiency; it can save, output, query and print data.

It strictly complies with the relevant standards at home and abroad. The detection accuracy is high, the data is accurate, the detection speed is fast, and the detection efficiency is 0-99.999%.

The cold-generating aerosol generator is used to produce continuous and stable aerosol particles, which is convenient for filling the solution.

The whole process of particle leakage prevention design protects the safety of experimenters.
