Mask sealing tester

Definition:

A device that measures the dust concentration on the outside and inside of the mask separately, 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, a test guide or tube fitting kit should be used.

Scope of application:

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.

Research on the Inspection, Training, and Teaching of Mask and Face Mask Tightness

Performance evaluation of respiratory protective masks (PAPR)

Self contained breathing apparatus tightness test

Gas mask tightness test

Feature:

1. Use one detector (particle counter) to automatically switch and continuously measure the number of particles indoors (outside the mask) and inside the mask. This can reduce errors caused by differences in detector characteristics.

2. Provide three modes: tightness testing mode, tightness inspection mode, and practice mode, which can be distinguished and used according to various purposes.

3. The test guide can be used separately for measurement (without damaging the mask) or the tube joint kit can be used for measurement (with holes drilled on the mask).

4. Equipped with a heating tube to prevent condensation of water vapor during exhalation and the formation of water droplets.

5. Comes with RS-232C output function for outputting measurement data.

6. The wearing condition of the mask can be confirmed through a mirror.

Product Features:

1. Easy to operate and convenient to use

2. Independent operation type - no need for external computer connection

3. Optional mask sampling adapter allows for tightness testing of various masks

4. Color touch screen can be operated with fingers or a pen

5. FitPro+TM fit testing software can automatically complete the test

6. External computer can generate reports and print tightness test cards

7. The tightness coefficient is greater than 10000

8. Calculating the sealing factor of masks using microscopic particles in ambient air

9. Provide interactive training tools for initial and subsequent training
