2채널 비저항계 HE-960RW-GC

개요

2가지 샘플의 비저항을 동시 측정,동시 출력하고 내약품성이 우수한 센서를 사용하여 정밀한 측정을 합니다.

기능

  • 2채널 동시 측정 - 1대로 센서 2개를 연결하여 비저항을 동시 측정 및 표시
  • 고정밀한 온도보상 - 백금 온도저항 (Pt1000Ω)의 편차를 입력하는 기능으로 온도 교정을 하지 않고 ±0.2℃이내의 정밀한 온도 측정이 가능하며 기준 온도계를 이용 온도교정도 가능
  • 2채널 출력 - 2채널 각각의 비저항과 온도를 출력
  • 내약품성 유리카본센서 사용 - 재질은 카본 100%로서 불산이나 과산화수소와 각종 세정액에 우수한 내약품성
  • 아이콘 상태표시 - 계기의 상태를 알기 쉽게 아이콘 표시
  • 비밀번호 설정기능
  • C24V전원

Communication output

RS-485 input/output

Calibration function

Resistivity : input of cell constant correction coefficient (parameter input)Temperature : Calibrated by comparing with the reference thermometer

Transmission output hold feature

Selectable from the Previous value hold and the Optional value hold.(However, only the previous value hold is available in the maintenance mode.)

Self-diagnosis function

・Sensor diagnosis error (short-circuit and disconnection of the temperature sensor)・Out of the measurement range・Converter error

Temperature compensation

・Based on the temperature characteristics of ultra-pure water (reference temperature:25°C)・Based on the reference temperature and user-defined temperature coefficient(reference temperature : 5 to 95°C, temperature coefficient : ±5%/°C)・No temperature compensation

Temperature compensation range

0 to 100°C
