The Synthetic Blood Penetration Resistance Tester is one of the most popular products in Qinsun's textile testing equipment. Today, I will tell you some basic knowledge about the Synthetic Blood Penetration Tester, so that you can know how to choose a suitable equipment if you need it in the future.
The protective clothing material was tested with synthetic blood under continuously applied pressure, and the penetration of synthetic blood on the material was visually inspected.
Synthetic blood penetration tester for medical protective clothing is mainly used to test the resistance of protective clothing to synthetic blood penetration under different test pressures.The synthetic blood penetration tester for protective clothing is suitable for measuring the resistance of daily work clothes, surgical clothes, isolation gown and protective clothing to synthetic blood penetration under different test pressures.
