Mask Respirator Breathing Resistance Tester usage and guide

Mask Respirator Breathing Resistance Tester , also known as fabric air resistance tester, is mainly used to measure the air penetration resistance of textiles, cotton wool, space cotton, etc. It is an important means to identify the comfort and hygiene of clothing and textiles, especially medical textiles. one. It is widely used in polymer material production enterprises, printing and dyeing industrial enterprises, textile inspection departments, scientific research units, textile colleges, etc.

 

 

The main purposes of Mask Respirator Breathing Resistance Tester are 2 points:

1. Mainly used to measure the air penetration resistance of textiles, masks, cotton wool, space cotton, etc.

2. Identify the importance of comfort and hygiene of clothing and textiles, especially medical textiles

One of the most important means.

 

Mask Respirator Breathing Resistance Tester features 5 points:

2. PLC control system, more efficient and reliable, programmable 7-inch color LCD touch screen, realize control, detection, calculation, data display and other functions.

3. The instrument is equipped with a large flow imported flowmeter, which has high accuracy, good data repeatability and stable performance.

4. Super power suction pump fixtures are interchangeable

5. The instrument is equipped with a super-powered evacuation pump, and the fixture is equipped with a variety of test fixtures to choose from, which can meet a variety of testing needs. In addition, it is equipped with overload protection and leakage protection, which is safe and reliable.

 

 

Applicable standards:

GB 19083-2010 Technical requirements for medical protective masks

 

5 things you must pay attention to:

1. During the test, if the air compressor starts frequently, it indicates that the gas loss is large, which is normal.

2. If you observe the word "ERROR" on the airflow resistance indicator after starting the test, it means that the air resistance of the sample has exceeded the set value of 500Pa. You must immediately press the "Test End" button to protect the instrument.

3. All parameters of the air resistance display table have been set, and non-professional maintenance personnel shall not modify it without authorization.

4. The flowmeter must be used within the flow range, and it is strictly prohibited to use it over the range.

5. If there is too much dust and impurities on the rotor in the flowmeter, which affects the accuracy of the reading, open the back cover of the instrument, open the manual ball valve in the box, and then connect the air source to clean the flowmeter. (In normal use, the ball valve in the box must be closed.)
