Mask tightness tester

Product Details

Tightness is an important indicator for evaluating the protective performance of masks. Ordinary users often only focus on common issues such as the protective properties of masks against particulate matter, while neglecting the individual issue of whether the mask matches the user. Even if factors such as product characteristics and usage environment are considered, dust masks may weaken their protective effect due to being unsuitable for the user.


Therefore, the tightness testing of dust masks is a necessary step in evaluating dust masks. When consumers purchase dust masks in their daily lives, they need to consider the performance of the product comprehensively from all aspects in order to effectively maximize the effectiveness of dust masks.


The tightness of a mask is usually expressed as the total leakage rate, which is the ratio of the concentration of the simulated agent that leaks into the mask from all mask components, including filtering elements, when the subject inhales under laboratory specified testing conditions, to the percentage of the simulated agent concentration in the inhaled air. The lower the total leakage rate, the higher the tightness.


Introduction:

The quantitative fit test of coordinated movements can be used as a method to select a mask that fits one's face. In the tightness testing mode, follow the pre-set actions, measure in order, and display the test results of each action and the comprehensive measurement results of all actions.


Definition:

A device that measures the dust concentration on the outer and inner sides of a mask, and calculates the intrusion rate (leakage rate%) of dust inside the mask based on the results. The experimental particles use general dust suspended indoors. When measuring the dust on the inside of a mask, use a test guide or a fitting kit.


Applicable scope:

There is no other tightness tester that can quantitatively test the tightness of all types of respirators. This tightness tester can perform tightness testing on gas masks, SCBAs respirators, and other types of respirators.
