Medical Face Mask Air Exchange Pressure Difference Tester G289 meets the standard requirements, which is YY0469-2004 "Medical surgical mask technical requirements" and YY 0969-2013 "Disposable medical masks", medical face mask air exchange pressure difference tester is measured by gas pressure difference on both sides of the mask (ie the damping from the mask exert to the airflow) to determine the breathability of the mask, and the instrument test results is accurate. source:https://www.testerinlab.com/ Features: 1. Adopt suction air source as the power source of the instrument, not limited by the space of the test site; 2. Equipped with a precision differential pressure sensor, which digitally displays the pressure difference on both sides of the sample; 3. The special sample holder ensures that the sample is firmly held. #medicalmaskdifferentialpressuretester #airexchangepressuredifferencetesterofmask #airexchangepressuredifferencetesterofmask #maskgasexchangepressuredifferencedetector #pressure #pressuretest #qinsun

edical Face Mask Synthetic Blood Penetration Resistance Tester G286 is used to determine the resistance of medical protective masks to penetration by synthetic blood at different test pressures,and can also be used to determine the resistance to blood penetration of other coating materials. https://www.qinsun-lab.com/ Usage: Medical Face Mask Synthetic Blood Penetration Resistance Tester G286 is used for anti-synthetic blood penetration of medical surgical masks, and mainly used in the field of medical protection products. It can also be used for other textile coating material determination.

High Accuracy Bacterial Filtration Efficiency (BFE) Tester Of Medical Masks G299 $2,000.00 - $4,000.00/ set |1 set/sets(Min. order) source:http://www.thentest.com/ source:https://standard-groups.com/en/ source:https://testerinlab.com/ High Accuracy Bacterial Filtration Efficiency (BFE) Tester Of Medical Masks G299 is to determine the bacterial filtration efficiency (BFE) of medical face mask materials by employing a ratio of the upstream bacterial challenge to downstream residual concentration of the tested medical face mask materials. The Bacterial Filtration Efficiency Tester provides certain flow rate of bacterial aerosol. The operator can measure the number of colony forming units passing through the medical face mask material, which is clamped between a six-stage Anderson cascade impactor and an aerosol chamber, expressed as a percentage of the number of colony forming units present in the challenge aerosol. Usage: Mask Bacterial Filtration Efficiency Tester is suitable for fast, accurate and stable detection of particulate filtering efficiency of various medical and daily protective masks, respirators, etc. tag:bacterial filtration efficiency tester,mask bacterial filtration efficiency tester,bacterial filtration efficiency tester of mask,bacterial filtration efficiency test equipment,mask bacterial filtration efficiency detector,bacteria filtration efficiency tester,bacterial filtration efficiency tester of face mask,mask bacterial filtration efficiency (bfe) detector,bacterial & viral filtration efficiency tester,mask bacteria filtration efficiency tester #bacterialfiltrationefficiencytester #maskbacterialfiltrationefficiencytester #qinsun
