450cm / S Medical Mask Synthetic Blood Penetration Tester

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.
