공업용 비저항계 HE-480R

개요

공업용 비저항계 HE-480R은 고정밀도 온도보상 기능을 탑재한 비저항계입니다.
반도체분야를 비롯해 전자·식품·의약품등의 분야의 제조공정에서 사용되는 초순수의 연속 모니터링에 최적입니다.

기능

  • 고정밀도로 온도 보상
    온도보상 소자에 백금저항체(Pt1000Ω)를 적용했습니다.
  • 기준온도 수동설정이 가능
    온도 보상의 기준온도를 임의로 설정할 수 있으므로, 초순수의 측정 등 공정조건에 맞춰서 사용 할 수 있습니다.
  • Pb free
  • 환경공해를 저감하기 위해서, PCB에 사용되는 땜납을 Pb free화하고 있습니다.
