● 두개의 NDIR 가스 필터와 하나의 파라마그네틱 산소 센서 장착.
● 각각의 가스 채널을 위한 개별적인 Microprocessor
● 분리된 span과 sample 가스 흡입구
● 9000MGA는 NDIR 방식으로 측정하는 두가지 가스와
파라마그네틱 센서로 측정되는 산소를 각각의 분리된
Microprocessor와 디스플레이로 보여주며, 더욱이 스팬과
샘플입력까지 개별적이므로 하나 또는 그 이상의 여러 가지
가스 분석기로 이용할 수 있다.
● 0~50ppm에서 100%까지의 넓은 측정범위
● 3U 높이의 19인치 rack mount 케이스
● RS232 리모트 콘트롤, 0 - 10V와 4 - 20mA 출력
● 측정가스 : CO2, CO, CH4, N2O, SF6, NO, SO2, HCL
