제품설명

개요

호리바의 독자적인 측정 방식을 응용한 새로운 UV탁도계입니다. 수질의 유기물을 측정하는 수질감시나 프로세스 라인중에서의 유기물 모니터등으로 사용할 수 있습니다.

기능

  • 수질의 더러움에 의한 영향을 셀 회전 제로점 체크 방식으로 드리프트가 없습니다.
  • 1대로 0~0.1Abs의 저농도부터 0~5.0Abs의 고농도까지 폭넓은 측정레인지로 측정합니다.
  • 대화식 메뉴로 쉽게 사용가능
  • 데이타 메모리 기능으로 1시간 간격으로 1년치의 데이타를 메모리 할 수 있습니다. 또 CF카르를 사용해서 PC로 데이타를 관리가 가능합니다.
  • 측정 셀 Wiper 세정으로 오염에 의한 오차를 최소화합니다.
