近年来,由南京分析仪器厂推出的替代产品HW-005型红外线气体分析器,较好地突破了传统的光色式检测系统的局限性。采用双光源、双光路交替断续切光的、固定相位的高效检测系统。由于采用双光源、双光路,光源灯丝易损,因而HW-005型红外线分析器在光源灯丝损坏后进行更换修理,就不能象一般光源灯丝更换一样,否则在调试通被测气体时 In recent years, the Nanjing Instrument Factory launched an alternative product HW-005 infrared gas analyzer, a better break through the limitations of the traditional light-color detection system. Using dual light source, dual optical intermittent intermittent cutting, the phase of the highly efficient detection system. Due to the dual light source, dual optical path, light source filament vulnerability, so HW-005-type infrared analyzer after the replacement of filament damage to the filament can not be replaced as the normal light source filament, or pass through the test gas
