Description
THE MEDICAL MASK SYNTHETIC BLOOD PENETRATION TESTER IS MAINLY USED TO MEASURE THE RESISTANCE OF MEDICAL MASKS TO SYNTHETIC BLOOD PENETRATION UNDER DIFFERENT TEST PRESSURES, AND CAN ALSO BE USED TO DETERMINE THE BLOOD PENETRATION RESISTANCE OF OTHER COATING MATERIALS. DURING THE TEST, A CERTAIN AMOUNT OF SYNTHETIC BLOOD IS SPRAYED AT A CERTAIN PRESSURE AND DISTANCE TO ONE SIDE OF THE MASK UNDER TEST IN THE HORIZONTAL DIRECTION, AND THE PENETRATION OF SYNTHETIC BLOOD ON THE OTHER SIDE OF THE MASK IS OBSERVED.
FEATURES:
THE MASK FIXTURE IS A METAL HUMAN HEAD MODEL, WHICH CAN FULLY SIMULATE THE ACTUAL USE STATE OF THE MASK.
THE METAL HUMAN HEAD MOLD CAN ROTATE AT A CERTAIN ANGLE, WHICH IS CONVENIENT FOR SAMPLE CLAMPING.
SPECIAL SPRAY CONTROL DEVICE CAN SPRAY A CERTAIN VOLUME OF SYNTHETIC BLOOD WITHIN THE CONTROLLED TIME.
THE INSTRUMENT INCORPORATES AN AIR SOURCE THAT CAN PROVIDE (700 ± 25) KPA STABLE AIR PRESSURE, WHICH IS NOT AFFECTED BY THE SPACE OF THE TEST SITE.
IT CAN SIMULATE THE LIQUID EJECTION SPEED CORRESPONDING TO HUMAN BLOOD PRESSURE
THERE IS A FIXED TARGET PLATE, WHICH CAN BLOCK THE HIGH-PRESSURE PART OF THE SPRAYED LIQUID FLOW, AND ONLY LET THE STEADY-STATE FLOW PORTION BE SPRAYED ON THE AREA SAMPLE, WHICH INCREASES THE ACCURACY AND REPEATABILITY OF THE TEST.
THE INSTRUMENT INCORPORATES IMPORTED SPECIAL ALUMINUM BRUSHED PANEL WITH METAL BUTTONS, WHICH IS SENSITIVE TO OPERATION AND NOT EASY TO DAMAGE.
THE 7-INCH COLOR TOUCH SCREEN DISPLAYS THE TEST PARAMETERS, AND THE MENU-TYPE OPERATION MODE IS AS CONVENIENT AS A SMARTPHONE.
THE CORE CONTROL COMPONENTS INCORPORATES MICROELECTRONICS 32-BIT MULTI-FUNCTION MOTHERBOARD.
THE INSTRUMENT CODE INCORPORATES 304 STAINLESS STEEL, WHICH IS DURABLE, NEAT AND CLEAN IN APPEARANCE.
SPECIFICATIONS:
SPRAY DISTANCE: 300 TO 310 mm
NEEDLE INNER DIAMETER: 0.84 mm
