PAS Analyzer

Photo acoustic spectroscopy

The TRACE-GAS PAS analyzer combine reliability, speed and ease of use in one device. Developed for the calibration-free and direct measurement.

  1. Key Features
    • no interfering signal an extremely accurate results
    • low sample volume and small cell size
    • huge price advantage
    • low amount oft drift
  2. Applications
    • immission in ambient air
    • site selection of measuring stations
    • detection of nitrogen oxide sources
    • building of measuring networks
