DRK265 Mask Dead Cavity Tester

Product details

Application Range:

Used for the detection of dead cavity of respirator, that is, the volume fraction of CO2 in inhaled gas

Standard:

GB 2626--- Respirator self-suction filter respirator against particulate matter.

Instrument Feature:

1、The test process is completely controlled by the computer program, which realizes automatic detection, automatic recording and automatic calculation of the change of the carbon dioxide concentration value of the inhaled gas during the whole test process. It is easy to operate and easy to use.

2、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.

3、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.

4、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.
