Meltblown Nonwoven Test: N95 Particle Filtration Efficiency (PFE) Tester

Face Mask Particulate Filtration Efficiency Tester is designed o test the filtering efficiency of particulate protective masks and medical masks and to determine the resistance of ordinary fabrics and medical protective masks to the constant flow of airflow. The PFE tester with particle generator can provide sodium chloride particles and paraffin oil particles. It can measure the particle penetration, filtering efficiency and the breathing resistance delta P. It is widely used in quality control, research and development, certification, manufacturing or testing industry, etc.


 It is used to detect the filtration efficiency of particulate matter such as daily masks and filters.It is applicable to medical equipment inspection center, safety protection inspection center, labor protection inspection center, drug inspection center, disease prevention and control center, hospital, mask and respirator manufacturer, etc.
Features of Face masks particle filtration efficiency (PFE) tester:
Using a cold aerosol generator to produce continuous and stable aerosol particles, convenient for filling the solution.
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.
Equipped with aerosol particle neutralization device.
The pneumatic clamp is equipped with a protection device, which is safe and convenient to use.
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.
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.

How To Process The Elmendorf Tear Strength Test

The Elmendorf tear tester has been developed specially for the paper industry and is outstanding for simplicity of operation and high measurement accuracy. The exchangeable pendulum is equipped with a pneumatic sample clamp. The initiation and return of the pendulum, as well as sample cutting is completely automatic. The device is operated via an integrated touch screen, where the test method can be selected, specific settings can be adjusted, and, after the measurement, results and statistics can be  displayed.Each pendulum is supplied with the appropriate control weight so that, with the help of the service program, it can easily be checked for functionality and balance. The Elmendorf tear test Procedure:     Cotton fabric was taken.     Warp and weft direction of the fabric was identified.     Two strips were cut from the fabric in both directions having dimensions of 100 x 63.5 mm.     The sample was then fixed in the jaws of the ...

Comparative analysis of water-cooled and air-cooled xenon lamp aging tester

Xenon lamp aging test chamber is the core component of using the box full sunlight spectrum xenon lamp tube simulation, under different environmental conditions to simulate the material aging law, through the experimental results to evaluate weather resistance of materials and products. This paper focuses on the comparative analysis of the advantages and characteristics of the water-cooled and air-cooled xenon lamp aging testing machine. Air-cooled xenon lamp aging test machine : A circular wind is used to cool the heat-trapping xenon lamp tube. Air-cooled xenon lamp tubes used in air-cooled xenon lamp aging test box, generally a typhoon cold xenon lamp aging test chamber is equipped with three air-cooled xenon lamp tubes, and table 1 air-cooled xenon lamp weather-resistant chamber equipped with xenon lamp tubes. The power of the air-cooled xenon lamp tube is generally 1.8kw, and the length of the lamp tube is 340mm compared with that of the water-cooled xenon lamp. The diameter of...

Correct Use Of Color Assessment Cabinet

Observation Angle: The following points are all the facilities required for the Color Assessment Cabinet , and the viewing Angle will directly affect the evaluation results. According to international standards, there are only two observable angles that can be used. They are: A, zero light source and 45 degrees observation (0 °, 45 °), the light from zero (vertical) incident Angle on the sample, sample watchers from 45 degrees. B, light source and 45 ° inclined channel 45 degrees of light source, zero observation (0 °, 45 °), the layout must use specific 45 degrees of inclined (45 ° Fixed Angle table) making from 45 degrees of light source on the samples, sample watchers from zero (vertical). The location of the 45 ° light samples: Regardless of any of the above observation methods, it is important to note that the test sample is placed in the middle of the light box as far as possible to reduce the influence of the external light source. In addition, the most important thing...
