PORTABLE GAS ANALYSER

Probably the gas most commonly analysed in related
geoscience, environmental science and atmospheric
science 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 to 10ppm resolution for the
0-2000ppm instrument.
