Commodity name: Particle Protection Effect Tester

PPP-2020

Function
It is used to test the protective effect and respiratory resistance of respirators.

Principle
Wear the mask to be inspected on the headform，and place the standard head form in the test chamber was filled with Salt aerosol or oily aerosol with standard particle size and concentration. A sinusoidal airflow was used to simulate breathing. The concentration of salt aerosol or oil aerosol before and after the mask was detected by high-frequency sampling with a photometer, and the protective effect of the mask on the particulate matter was calculated.

Standards
GB/T6165-2008 、GB/2626-2006 、GB/T 32610-2016

Characteristics
● Using a built-in high-precision laser scattering photometer, guarantee accurate measurement of aerosol concentration.
● Respirator protection effect test and respiratory resistance detection test can be performed at the same time.
● The standard salt and oil aerosol generator can automatically generate continuous aerosol with specific particle size and concentration；
● A built-in precision flow controller, ensure more accurate flow control.
● Automatic control of the test process, real-time measurement of aerosol concentration, resistance, flow, automatic calculation of filtration efficiency.
● Provide a function to save, query, and print test data in the database.
● 10.1-inch color high-resolution touch screen, with an intuitive interface, easy to use.
● Leakproof design of test chamber, safer when open and close glass door.
