제품명 공업용 전도도 측정기 HE-480H(고농도 용)

제품설명


개요

공업용 전도도 측정기 HE-480H는 4전극법을 사용하고 0~50S/m의 측정범위로 고농도를 측정합니다. 다양한 용도로 폭넓게 사용가능합니다.

기능

  • 50S/m(500mS/cm)까지의 폭넓은 측정범위 : 여러가지 용액의 농도관리부터 염분 농도 측정이나 액체비료의 관리까지 여러가지 용도로 사용
  • 해수 염분, NaCl 염분 환산 기능 : 전도도의 환산값을 이용하여 염분농도를 환산해서 표시
  • 다양한 온도 보상 : 샘플의 온도 특성에 따른 온도 보상 설정이 가능
  • 센서의 상태를 자동으로 판단 : 센서의 감도를 자동적으로 판단하여 표시
