Product Overview
The Picarro G2301 gas concentration analyzer can simultaneously measure carbon dioxide (CO2), methane (CH4), and water vapor (H2O), with a sensitivity of parts per billion (ppb). The drift generated for atmospheric science, air quality, and quantitative emission applications can be ignored. This analyzer meets the performance requirements of the World Meteorological Organization (WMO) and the Integrated Carbon Observing System (ICOS) for atmospheric monitoring of CO2 and CH4.
Product Features
• Simultaneous and continuous measurement of three atmospheric trace gases
• Billion parts per billion (ppb) sensitivity, accuracy, and precision, with extremely low drift
• Complies with the international environmental and atmospheric monitoring requirements of WMO and ICOS
• Equipped with water correction function, automatically reporting dry gas mole fraction
