PGA

Portable Gas Analyzer

Simple, reliable, absolute, field portable analyzer for a variety of applications & measurement of various gases

The PGA Portable Gas Analyzer is a battery portable instrument for the intermittent, short-term monitoring of gas concentrations. Single or dual gas versions are available utilizing a highly accurate infra red gas analyzer and/or an electrochemical cell. The instrument can be configured for various gases.

Features

  • Proven IRGA technology with optional electrochemical cell
  • Integral sample pump
  • Battery portable
  • The PGA may be configured to measure the following gases:
    • Methane
    • Oxygen
    • Carbon Monoxide
    • Nitric Oxide
    • Nitrous Oxide
    • Sulphur Dioxide
    • Sulphur Hexafluoride
    • Ammonia
  • Ethane
  • Propane
  • Butane
  • Pentane
  • Hexane
  • Heptane
  • Freons
  • Hydrogen
  • Hydrogen Sulfide
  • The new PGA is the latest addition to the ADC BioScientific range of Geoscience research analyzers. Weighing just 5kg and offering 8 hours of continuous use, the battery operated PGA is set to offer new levels in portability and performance for a field portable gas analyzer.

    Probably the most commonly analyzed gas in related geoscience, environmental science and atmospheric science studies is CO2. The PGA is available in ranges from 0-2000ppm CO2 to 0-100% with a resolution of 0.5% full scale deflection (fsd). This corresponds to10ppm resolution for the 0-2000ppm instrument.

    The PGA suitable for a wide range of experimental studies including elevated CO2 studies, atmospheric CO2 monitoring, FACE experimentation and measuring high concentrations in natural CO2 springs.
