Mask tightness tester, mask adaptability tester

Mask tightness tester, can quickly complete the tightness of mask and other respirator experiments, to ensure good protective performance, in line with Chinese respirator standard GB2626-2019 standard, OSHA / CSA standard and GB 19083-2010 Medical protective mask jointly issued by the General Administration of Quality Supervision, Inspection and Quarantine of China, tightness (suitability test): mask design should provide good tightness, mask total fit factor should be no less than 100, the test requirements was formally implemented on August 1,2011.

detailed introduction

How to choose a high-quality mask not only depends on the filtration efficiency of the mask, but also to confirm whether the mask and the face are completely close, otherwise the aerosol particles such as bacteria not filtered by the mask will be inhaled from the inadequate close.Therefore, it is critical to check the wearing status of masks. European and American countries have listed the application test of masks as a strong inspection item.

For example, the N95 masks are one of nine kinds of particulate matter protective masks certified by the NIOSH (National Institute of Occupational Safety and Health)."N" indicates non-oil resistance."95" means that when exposed to a specified number of special test particles, the concentration of particles inside the mask is more than 95% lower than the concentration of particles outside the mask.The N95 is not a specific product name, which meets the N95 standards and passes the NIOSH review can be called an "N95 type mask".

In addition to the filter efficiency of masks, the tightness of masks and face is one of the important factors that determine the use effect of masks. Different types of masks are greatly different from the suitability of human face.Therefore, the suitability test of the masks should be conducted first before using them.When testing the face tightness, ensure that air can enter and exit through the mask at the edge of the face.

Mask tightness tester, can quickly complete the tightness of mask and other respirator experiments, to ensure good protective performance, in line with Chinese respirator standard GB2626-2019 standard, OSHA / CSA standard and GB 19083-2010 Medical protective mask jointly issued by the General Administration of Quality Supervision, Inspection and Quarantine of China, tightness (suitability test): mask design should provide good tightness, mask total fit factor should be no less than 100, the test requirements was formally implemented on August 1,2011.

Using CNC technology, suitable for disposable filter mask tightness test of 100 / 99 / P3 / P 3 / HEPA series mask (including N95 / N90 / KN95 and other abandoned dust mask), virus mask / breathing mask, half mask, full mask tightness test, independent or computer control, five countries language switch display, with a variety of communication interface (USB, Ethernet), can also enable WIFI, a computer can control four instruments.

Mask tightness degree tester

In order to prevent infection, and during labor work, workers must be protected from inhaled dangerous substances in the workplace, and they must wear masks and other breathing apparatus.

Combine your own facial characteristics to choose a respirator such as a mask, and evaluate the tightness between the mask and the face, to test whether there are gaps or leakage points that put workers at risk.It can quickly complete the tightness experiment of respirator and other respirator to ensure that it provides good protective performance.Safety experts will also develop protection plans and standards and regulations for the results of the density experiments.widely used in hospitals, manufacturing factories, production sites, fire workplaces and other testing institutions.
