Synthetic blood penetration tester for medical mask
Product introduction:
It adopts 5.7 inch (320 * 240) PLC colorful LCD touch screen,
Chinese menu display, high precision pressure sensor, AD
acquisition speed of 500KHz, internal code of 500000; high
precision clock chip, power off storage; PLC control dynamic
display of loading force value; overload alarm and shutdown
protection, It can print test data, and the protruding sample
fixing device can simulate the actual use state of the mask,
reserve the test target area without damaging the sample, and make
the synthetic blood distributed in the target area of the sample;
the special constant pressure injection device can spray a certain
volume of synthetic blood in the controlled time; the special
constant pressure injection device can spray a certain amount of
synthetic blood in the controlled time The volume of synthetic
blood; to block the high-pressure part of the jet liquid flow along
the part, only let the steady-state flow part spray to the sample,
which increases the accuracy and repeatability of the liquid speed
injected to the sample, nominal size, test, time, calibration, etc.
It fully meets the requirements of 4.6 in YY 0469-2011 technical
requirements for medical surgical masks.
