Non-woven Mask Respiratory Resistance Tester Technical indicators

Masks have become an essential product in our daily life. With the global outbreak of COVID-19 epidemic,  wearing masks every day has become one of the most effective and simple ways for us to protect ourselves. So, do you feel that your breathing is not smooth when you wear a mask?  Do you know what kind of mask can be regarded as a qualified mask?

After the mask is produced, it will undergo a variety of tests, which requires a lot of testing instruments, including Mask Tensile Testing Machine,Face Mask Field of Vision Tester,Mask burning tester,  etc. To some extent, these instruments determine whether masks are qualified products. Among them, the test equipment that determines the respiratory resistance of the mask is today's theme: Mask Breathing resistance testing machine.



Mask respiratory resistance tester Use of instrument

The respirator respiratory resistance tester is used to measure the inspiratory resistance and expiratory resistance of respirator and respirator protective equipment under specified conditions
Force. Applicable to the national labor protection articles inspection agencies and mask manufacturers for ordinary masks, dust masks, medical masks,
Related testing and inspection of anti-fog mask products.

Technical indicators

1. The instrument consists of an air source that can adjust the flow, a human head model specified by the standard, two sets of pipeline systems for inhalation and exhalation, and respiratory resistance Force measurement system, etc.
2. The flow sensor has high sensitivity and very small initial flow.
3. The flow sensor chip adopts thermal mass flowmeter without temperature and pressure compensation, which ensures the high-precision measurement of the sensor.
The measuring range of the flowmeter is 0 L/min ~ 100 L/min, and the accuracy is 2%.
4. Multiple sensors are integrated on a single flow sensor chip, which greatly improves the range ratio of sensors.
5. The flow sensor has high stability at zero point, high stability in full range, high accuracy in full range and excellent repetition
And has the characteristics of low power consumption, low voltage loss and fast response speed.
6. The data recorder adopts graphic dot matrix liquid crystal with resolution of 128×64, with all Chinese interface and convenient operation.
7. There is 4M memory in the data recorder for recording measured values.
8. The micro-pressure meter sensor adopts two-wire system with high precision and good stability; The explosion-proof design is safe and reliable.
9. The measuring range and zero point of the micro-pressure meter sensor are continuously adjustable externally, the damping is adjustable, there is no mechanical moving part, and the maintenance workload is less.
The micro-pressure measuring range is-1000 Pa ~ 1000 Pa, and the precision is 1Pa.
10. The whole instrument adopts special air circuit conversion element, which ensures the convenient and quick conversion of two sets of pipeline systems of exhalation and inhalation.
