Precise, accurate and fast analyzers for measurement of CH4, CO2 and H2O in ambient air.

Introduction

• ABB’s greenhouse gas analyzers report measurements of methane, carbon dioxide and water vapor simultaneously in various packages: the microportable GLA131-GGA and ultraportable GLA132-GGA versions are compact, crushproof and travel-friendly analyzers while the enhanced performance (EP) rackmount a, GLA331-GGA is designed for extra precision, accuracy and stability.

• As with all LGR-ICOS analyzers, the greenhouse gas analyzers are simple to use and offer a wide dynamic range. It measures ambient levels with extremely high precision while still being intrinsically accurate at concentrations 50 times higher. They are extremely rugged which makes them ideal for long-term greenhouse gas monitoring, eddy flux and soil flux studies, and wherever measurements are needed quickly and sensitively.

• The greenhouse gas analyzers begin recording data within 20 seconds after power on so users do not have to wait for a long warm-up period for the system to thermally equilibrate.
