1 summarize 1.1 Product introduction ZR - 1000 type mask bacteria filtration efficiency key performance
indicators (BFE) detector not only conforms to the requirements of
medical surgical masks technology YY0469-2011 appendix B in the
test method for filter efficiency (BFE) bacteria first B. 1.1 the
requirement of test instruments, but also conforms to the American
society for testing material ASTMF2100, ASTMF2101, the requirements
of the European EN14683 standards, innovative improvements were
made on the basis of this, with double pneumatic contrast sampling
method at the same time, improve the precision of sampling,It is
suitable for measuring and testing departments, scientific research
institutes, mask manufacturers and other relevant departments to
test the performance of mask bacterial filtration efficiency. 1.2 Product feature Negative pressure test system to ensure the safety of operators; Built - in peristaltic pump in negative pressure cabinet, A, B
two - way, six Andersen; The peristaltic pump flow can be set; The flow rate of bacteria-night spray of special microorganism
aerosol generator can be set. Good atomization effect; Embedded high speed industrial microcomputer control; 10.4 inches industrial high brightness color touch screen; USB interface, support U disk data storage; Cabinet built-in high brightness lights; Built-in leakage protection switch to protect the safety of
operators; Cabinet inner stainless steel whole processing molding, outer
plastic spray cold rolled plate,Heat preservation and flame
retardant between inner and outer layers; The front switch type glass door is convenient for the
experimenter to observe and operate.Detachable bracket, adjustable
bracket height; Supporting and moving dual purpose casters. 1.3 Execution standard Q/0212 ZRB003-2015 Mask bacterial filtration efficiency (BFE)
