DRK227 Synthetic Blood Penetration Tester for Medical Masks
Test items: Test the performance of synthetic blood penetration test
DRK227 Medical Mask Synthetic Blood Penetration Tester has a special constant pressure spray device that can spray a certain volume of synthetic blood in a controlled time.
Technical Index:
1. The convex sample fixing device can simulate the actual use state of the mask, leaving the test target area without destroying the sample, and distributing the synthetic blood in the target area of the sample.
2. The special constant pressure spray device can spray a certain volume of synthetic blood in a controlled time.
3. It can fully simulate the injection speed corresponding to the average human blood pressure of 10.6kPa, 16kPa, and 21.3kPa for testing.
4. It is equipped with a fixed target plate, which can block the high-pressure edge part of the sprayed liquid flow, and only let the steady-state flow part spray on the sample, which increases the accuracy and repeatability of the liquid velocity sprayed on the sample.
