The synthetic blood penetration tester for medical masks is mainly used to measure the resistance of medical masks to synthetic blood penetration under different test pressures, and can also be used to measure the blood penetration resistance of other coating materials..
During the testing process, a certain amount of synthetic blood will be sprayed horizontally at a certain pressure and distance towards one side of the tested mask, and the penetration of the synthetic blood on the other side of the mask will be observed.
This device is used for the anti synthetic blood penetration ability of medical surgical masks, mainly in the field of medical protective equipment, and can also be used for the determination of other textile coating materials.
Its application areas include but are not limited to:
Medical mask manufacturer;
Metrological verification department;
Research institutes;
The product inspection or quality control department of the manufacturing plant;
Third party testing platform;
Quality supervision and market supervision inspection units in various regions;

lThe mask fixture is a metal human head mold that can fully simulate the actual usage state of the mask.
lThe metal human head mold can rotate at a certain angle for easy sample clamping.
lA specially designed spray control device can spray a certain volume of synthetic blood within a controlled time.
lThe instrument can provide(700±25)kPaA stable gas source that is not affected by the current space of the testing site.
lCan simulate human blood pressure10.6kPa、16.0 kPa、21.3 kPa(i.e80mmHg、120mmHg、160mmHg)Test the corresponding liquid jet velocity.
lThere is a fixed target plate that can block the high-pressure edge of the sprayed liquid flow, allowing only the steady-state flow to be sprayed onto the surface sample, increasing the accuracy and repeatability of the experiment.
lThe instrument adopts imported special aluminum brushed panel, equipped with metal buttons, which are sensitive to operation and not easily damaged.
l 7The inch color touch screen displays test parameters, with a menu based operation mode that is as convenient as a smartphone.
lThe core control components are manufactured by STMicroelectronics32Multi functional motherboard.
lInstrument coding adopts304Stainless steel, durable and tidy in appearance.;
