전류 제한형 산소 분석계 OX102

OX102 산소 분석기는 단일 분석기에서 ppm 에서 % 수준의 산소 농도를 측정하며 질소 리플 로우로 및 반도체 공장과 같은 응용 분야의 ppm 수준 측정에 이상적입니다.

지르코니아 산소 센서는 제한 전류 원리에 기반을두고 콤팩트하면서도 고성능을 유지하는 방법을 사용합니다. 센서는 직접 삽입으로 설치하도록 설계되었습니다.
샘플 가스가 질소 리플 로우로와 같은 응용 분야에서 수 ppm 수준의 유기 용매를 포함 할 경우 선택적 시료 샘플링 장치가 필요합니다.

  • One instrument capable of measuring from 0 - 100 ppm to 0 - 25% oxygen
  • Simple one touch calibration
  • Self diagnostics assure high reliability
  • One touch sensor replacement
  • Compact size

Measuring Principle

Current flowing in the Zirconia fixed electrolyte causes oxygen to move from the negative to positive electrode (acts as an oxygen pump). If the flow of oxygen to the negative electrode is restricted by the alumina substrate then a current saturation area is created and the same current flows regardless of the applied voltage. The current that flows is called the limiting current. When a fixed voltage is applied, the current flow is proportional to the oxygen concentration.
