휴대용 가스 MFM

검증 또는 캘리브레이션을 위하여 운영 프로세스를 중단하는 것은 필요 악입니다. Alicat의 휴대용 유량 교정기는 가동 중단 시간을 줄이고 공정 중단을 줄임으로써, 이 절차를 보다 더 만족스럽게 만듭니다. 넓은 유량 범위에서 여러 가스에 대한 실시간 측정 값을 확인 할 수 있습니다.

특징

» 충전식 배터리로 휴대 가능한 MFM (풀 충전으로 18시간 작동)

» 빠른 응답속도 (<10ms)

» Warm-up 타임 불필요, 1초 내에 측정 준비 가능

» 컴퓨터 또는 PLC와 함께 사용 가능 (컴퓨터 또는 PLC 없이 단독 유닛으로도 사용 가능)

» 모든 유량 데이터를 하나의 스크린에서 확인 가능 (Flow, Pressure, Temperature)

» 디지털 및 아날로그 출력
