Product OverviewncQTextile Testing Instruments, Testing Equipment Manufacturer

This device is designed and manufactured in accordance with GA124 and GB2890 standards and is used for dead space testing of fire respirators. The principle of the test is determined by measuring the CO2 content of the inhaled gas.ncQTextile Testing Instruments, Testing Equipment Manufacturer

【Operation Principle】ncQTextile Testing Instruments, Testing Equipment Manufacturer

The main components of the test Devices include: test head mold, mechanical artificial lung with electric valve, connecting pipe, flow meter, CO2 gas analyzer and control system.ncQTextile Testing Instruments, Testing Equipment Manufacturer

The test device is driven by the low-speed motor of the detection device through the control system to reciprocate the artificial lung to simulate the real human breathing process. The push stroke is equivalent to inhaling and the backward stroke is equivalent to exhaling. As for the shape of the head at the top of the cabinet, these two processes complete the breathing process. Send a certain amount of highly concentrated CO2 during inhalation and use a CO2 monitor to detect the entire breathing process.ncQTextile Testing Instruments, Testing Equipment Manufacturer
