Dead space tester for protective mask type JG057R5vTextile Testing Instruments, Testing Equipment Manufacturer

【Product Overview】R5vTextile Testing Instruments, Testing Equipment Manufacturer

This device is based on the standard GA124 and GB2890 Designed and manufactured for dead space testing of pressurized fire respirators. The test principle is determined by measuring the CO2 content of the inhaled gas.R5vTextile Testing Instruments, Testing Equipment Manufacturer

【Operation Principle】R5vTextile Testing Instruments, Testing Equipment Manufacturer

The main components of the test apparatus include: head, mechanical artificial lung with electric valve, connecting pipe, flow meter, CO2 gas analyzer and control system.R5vTextile 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.R5vTextile Testing Instruments, Testing Equipment Manufacturer
