APSA-370 [High Sensitivity Model]

Ambient Sulfur Dioxide Monitor

APSA-370 High Sensitivity Model is a gas analyzer for measurement of sulfur dioxide (SO2) at extremely low parts per billion level concentration.The analyzer has applied ultraviolet fluorescence (UVF) method. It has incorporated aromatic hydrocarbon cutter to reduce the interfence from the coexisting hydrocarbons. In addition, a unique design of the measurement cell enables high sensitivity and high stability of the measurement by achieving low background noise. Measurement range 0 - 10 / 20 / 50 / 100 ppb and Lower Detection Limit 0.1 ppb enables application of the analyzer for the cleanroom airborn molecular contamination monitoring, ambient air background monitoring, monitoring of the cultural property presenvation environment etc.

Application

  • Ambient air background monitoring
  • Cleanroom airborne molecular contamination monitoring
  • Monitoring of the cultural property preservation environment
