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.
