Picarro G2401 CRDS Analyzer
For the precise measurement of CO2, CO, CH4 and H2O in Air
The G2401 is a field-deployable analyzer for the parallel continuous measurement of the four atmospheric tracer gases CO2, CO, CH4 and H2O. It distinguishes itself through the smallest drift of all devices available for continuous measurement of greenhouse gases. With the precise measuring method, the high accuracy and the small drift it meets the WMO Data Quality Objectives for CO, CO2 and CH4. The integrated water correction feature automatically reports the dry mol fraction.
