How to regulate the use of artificial blood permeation tester?

The artificial blood permeation tester sprays a certain amount of synthetic blood with a certain pressure and distance along the horizontal direction to one side of the mouthpiece being tested, and observes the penetration of synthetic blood on the other side of the mouthpiece. The time and pressure that can be provided for the body fluid simulant for the sample under test to check whether there is visually detected synthetic blood penetration. It is suitable for determining the resistance of daily work clothes, surgical gowns, isolation gowns and protective clothing to synthetic blood penetration under different levels of test pressure.

Technical characteristics of the artificial blood penetration tester:

Negative pressure experimental system, with fan exhaust system and inlet and outlet air efficient filter to ensure the safety of the operator.

U disk to export historical data.

Pressure point pressurization method adopts automatic adjustment to ensure the accuracy of the test.

Industrial-grade high-brightness color touch screen.

Adopt imported pressure sensor, accurate data, high measurement accuracy. Volume data storage, save historical experimental data.

Special stainless steel penetration test tank to ensure firm clamping specimens, and to prevent synthetic blood spraying around.

The cabinet is equipped with high brightness lighting.

Built-in electric leakage protection switch to protect the safety of operators.

Cabinet inner layer of stainless steel processing molding, the outer layer of spray plastic cold-rolled plate, between the inner and outer layer of heat preservation, flame retardant.

Artificial blood permeation tester use specifications:

1、During the test, if the air compressor starts frequently, it means that the gas loss is large, which is normal.

2, if the test begins, observe the airflow resistance display table on the word ERROR, indicating that the sample gas resistance has exceeded the set value of 500Pa, you must immediately press the "test end" button to protect the instrument.

3, airflow resistance display table all parameters have been set, non-professional maintenance personnel shall not modify.

4, the flowmeter must be used in the flow range, strictly prohibit the use of over-range.

5, if found that the flowmeter rotor on the dust impurities too much, affecting the reading accuracy, then open the back cover of the instrument, open the manual ball valve inside the box, and then pass on the air source, the flowmeter cleaning.

6, the instrument manual does not appear in the adjustment valve, do not adjust the test process without authorization.
