Mask Respirator Breathing Resistance Tester

 Mask respiratory resistance tester is used to measure the respiratory resistance and expiratory resistance of respirators and masks under the specified conditions. Applicable to the national labor protection supplies inspection agency, mask manufacturers related inspection and inspection of ordinary masks, dust masks, medical masks, anti-fog mask products.

 
Application:
 
Mask & Respirator Breathing Resistance Tester can be used to determine the inspiratory and expiratory resistance of masks under specified conditions.Another additional function of this machine is flow impact test of the breather valve. The flow rate for inhale resistance test is 30L/min and 95L/min. The flow rate for exhale resistance test is 160L/min. And the flow rate for the flow impact test is 300L/min.
 
Standards:
 
EN149-2009 section 7.15, 8.3.4, EN 13274-3, GB 19083, GB 2626, NIOSH 42 CFR Part 84, JIS/T 8151
 
Features:
 
1. Touch screen control, English menu, man-machine dialogue mode, easy operation.
2. Built-in thermal printer, it is convenient to quickly print test results on site.
3. Two modes of breath detection and inhalation detection can be set.
4. The automatic switching device of the respirator pipeline solves the problem that the tester pulls out the
pipe and accidentally connects the pipeline when testing.
5. 3D printed standard head mold, which simulates the actual inhalation and exhalation of the human body,
improving the accuracy of the data.
 
Parameters:
 
Air Flow Meter Range:20~160L/min  Accuracy: 1%
Digital Differential Gauge Range:-1000~1000Pa  Accuracy: 1Pa

Determination of air permeability of a fabric-air permeability tester

Fabric air permeability is a measure to what extent it gives air passing through the fabric. Air permeability, a given area in the vertical direction of the air flow rate, a given time period, is measured by the fabric test area inside the pressure difference of the fabric. Basically, it depends on weight, thickness and porosity of fabric. The porosity of fabric is the demonstration of the air gap as a percentage within fabric. It has been important for especially the tent fabric, parachute fabric, raincoat fabric and garment, the fabric used in air bags, industrial filters and sail cloth. Moreover, when thermal properties of clothing and body interaction are taken into consideration, there has been the effect of air permeability. there is an instrument which is designed to test the air permeability of fabric on the market .it is air permeability tester . Air permeability is an important feature of fabrics (Sundaramoorthy et al., 2011) and is one of the main factors affecting the t...

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 ...

Classfication Of The Textile Testing

Textile testing is the term for a whole series of tests that examine the physical, mechanical and chemical properties of textiles. These tests are sometimes done before a textile goes into widespread use, or they're done on textiles arriving from other countries for sale in US markets. Countries like the United States have established standards for what should and should not be in textile products. Tests can show whether companies making textiles are in compliance or not. Many textile tests have many types. Some of them are physical tests, in which a sample of textile material is examined closely for feel and appearance. Such tests are done on individual fibers or strands of material and on yarns, threads made of several fibers twisted together. Textiles are subjected to light and other elements to see how they react. Some of these tests are done in a weather-ometer, a machine that tests for weathering and lightfastness of textiles. It's basically an enclosed box. Textiles...
