ABB GLA331 series

Enhanced performance rackmount gas analysers

ABB LGR ICOSTM Enhanced Performance GLA331 series integrates an internal thermal control and is described by ABB as performing “ultra-stable measurements with unsurpassed precision, accuracy, linearity, stability” and drift in a 9U rackmount package that can handle fast pump over times with fast-flow option and appropriate external pumps.

The pre-calibrated gas analysers provide reliable measurements at concentrations more than 20 times greater than typical ambient levels. Achieving measurements over the widest range of ambient temperatures, the ABB GLA331 series allows users to easily record steadfast data in the field.

Acoem Australasia (Ecotech Pty Ltd) is an official representative and distributor of ABB LGR-ICOSTM gas analysers in Australia and New Zealand. ABB LGR-ICOSTM was formerly known as Los Gatos Research (LGR).
