Тестер эффективности фильтрации твердых частиц медицинской маски

Particulate Filtration Efficiency PFE Detector

Application

It test evaluates the nonviable particle retention or filtration efficiency of filter media and other filtration devices at sub-micron levels. This test is performed for face mask and all filter material that allows 1 cubic foot per minute (CFM) flow to pass through it.

Specifications

Features

1, Using a cold aerosol generator to produce continuous and stable aerosol particles, convenient for filling the solution.

2, Measurement of aerosol concentration using a high-precision PM2.5 sensor. Anti-leakage design of whole particles to protect the safety of laboratory personnel. 2 sets of Aerosol generator:Salty aerosol generator and oily aerosol generator.

3, Equipped with aerosol particle neutralization device.The pneumatic clamp is equipped with a protection device, which is safe and convenient to use.

4, Configure temperature and humidity sensor, real-time display of ambient temperature and humidity(Temperature and humidity requirements:25℃±5℃,30%RH±10%RH).Equipped with glass rotor flowmeter, vacuum pump, laser dust particle counter.

5, Control system: The computer controls the test process, automatically collects data, and configures a special computer and test software.
The computer automatically tests the gas concentration and calculates the filtration efficiency. It can save, output, query and print the test data.
