Product Details
Surgical Mask And Protective Clothing Synthetic Blood Penetration
Resistance Testing Equipment
Product Introduction:
Mask Dead Cavity Detector is mainly used to detect the dead cavity of respirator, that is,
the volume fraction of CO2 in inhaled air.
The testing principle of the equipment is to detect, record and
calculate the change of the carbon dioxide concentration of the
inhaled gas during the whole test process.
Standards:
- GB2626-2019 "Respiratory Protective Products-Self-priming Filtering
Anti-particulate Matter"
- TAJ1001-2015 Dead Space Detection Project in "PM2.5 Protective
Mask"
- GB / T16556-2007 "Self-contained open-circuit compressed air
breathing apparatus" in the mask inhaled carbon dioxide gas content
Features:
- The test process of the respirator dead chamber tester is
completely controlled by the computer program, which realizes
automatic detection, automatically records and automatically
calculates the change of the carbon dioxide concentration value of
the inhaled gas during the whole test process. It is simple to
operate and convenient to use.
- During the test, there is no need to adjust the respiratory rate
and respiratory volume. As long as the simple parameter setting operation on the computer
can change the respiratory rate and respiratory volume, the
adjustment is very convenient and accurate.
- The one-way valve of control breathing channel adopts solenoid
valve set which is automatically controlled by the ventilator. Make the test result more accurate;
- All the data of the test process is automatically saved in the
computer, and the test report is automatically generated. The data
of the whole test process can be viewed through the computer at any
time, and the test result report of any time period can be printed
at any time.
