Synthetic Blood Penetration Tester Suitable For Testing The Resistance Of Protective Clothing To Synthetic Blood Penetration Under Different Levels Of Test Pressure

Main uses

The medical protective clothing synthetic blood penetration tester is suitable for testing the resistance of protective clothing to synthetic blood penetration under different levels of test pressure.
Working principle
Under continuously applied pressure, synthetic blood was used to test the protective clothing material, and the penetration of synthetic blood on the material was visually inspected.
Instrument features
The instrument uses a gas source that can provide a pressure of (20±1)kPa to continuously pressurize the sample, and is not restricted by the space of the test site.
2. The instrument is equipped with a pressure gauge to display the pressurized pressure, and the pressurized pressure is adjustable.
3. Use pressurized medium: compressed air.
4. The specially designed stainless steel penetration test chamber ensures that the sample is firmly clamped and prevents synthetic blood from splashing everywhere.
5. Square metal block mesh: Open space ≥50%; Bending ≤5mm at 20kPa.
6. Digital display timer, accuracy ±1 second.
7. The instrument is equipped with a clamp capable of generating a torque of 13.5Nm.
8. The structure of the instrument is the same as that of the "Schematic Diagram of the Test Instrument" and the "Structure of the Test Chamber" in the GB19082-2003 standard.
