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

Nonwovens automatic filtering efficiency tester, PFE Tester, Meltblown Filter Tester Warranty time: 12 months Model name: Particular filtration efficiency tester http://www.thentest.com/ filter material performance tester is used to quickly and accurately detect the resistance and efficiency performance of various flat materials, such as glass fiber, PTFE, PET, PP melt-blown composite filter materials. Product design conforms to many domestic and foreign industry standards such as EN1822-3: 2012, GB19083-2003, GB2626-2019 (KN95), IEST-RP-CC021.1. Main Features: The differential pressure measurement uses imported high-precision differential pressure transmitters, accurately measure the sample resistance The efficiency test uses Sujing high-precision photometer to detect the aerosol concentration in the upstream and downstream of the sample to ensure the authenticity and accuracy of the upstream and downstream samples. The generator system uses special nozzles to meet the generating of oil and salt aerosols. Polydisperse particle size distribution (optional monodisperse particle size) can occur, and the generating concentration can be adjusted quickly and stably Touch screen control, simple and intuitive operation, support for remote maintenance Test result is automatically system calculated, displayed, and printed out Main technical parameters: Test flow range is 15 ~ 100L / Min Test sample specifications: 100 cm2 / 12cm2 (PTFE / glass fiber strip), equipped with multi-specification fixtures (flat masks, 3D masks) Resistance test: range 0 ~ 1000Pa, accuracy can reach 0.01Pa, automatically return to “0” function Efficiency test: efficiency range 80% -99.999%; Dust sources: NaCl, PSL, DEHS, DOP Test time: resistance is tested separately for 10s, efficiency and resistance are tested simultaneously for 120s Power requirements: 220V, 50Hz, 1KW Air source requirements: 0.5MPa, 120L / Min Dimensions: 800 * 800 * 1600mm (width * length * height) Product weight: 100 Kg

The mask particle protection effect detector is placed in the volume of 500L self-cleaning detection chamber with national standard head model, the mask to be tested is worn on the head model, salt aerosol with a median mass diameter of 0.6μm and a concentration of 25mg/m3 and oil aerosol with a median mass diameter of 0.3μm and a concentration of 25mg/m3 are input into the self-cleaning detection chamber, and the head model makes a sine curve to simulate Breathing, using upstream and downstream photometer sampling to detect the concentration of salt aerosol and oil aerosol before and after the mask, and calculate the filtering efficiency of the mask particulate matter. Technical features: Mask particle filtration efficiency detection and breathing resistance detection integrated design, a machine multi-purpose. Self-cleaning test chamber configuration operating gloves, convenient for the replacement of masks to be tested. Three types of head mold compatibility design, head mold plug and play, easy to replace. External salt and oil aerosol generator can be controlled to control the concentration of particulate matter occurrence. Large touch display design, automatic display of respiratory flow curve and automatic calculation of particulate matter filtration efficiency. Full range of particulate matter leak-proof design to protect the safety of experimenters. Photometer long life laser light source, high precision photomultiplier tube detection. Photometer working time statistics, automatic prompting cleaning time. High efficiency filter use time statistics automatically, prompting the replacement of high efficiency filter. Historical data can be exported via U disk or printed via embedded printer. 9-30 ps: (WLJCDM809) https://www.qinsun-lab.com/Products/Application/Mask-Protective-cloth-Tester/ https://www.standard-groups.com/en/TextileGarment/836.html
