University of Leeds: Licor Li-7500 gas analyzer

Status: Not defined
Publication State:

Abstract

The University of Leeds' LI-COR LI-7500 open path gas analyser operates at infra-red wavelengths measuring the absorption due to carbon dioxide and water vapour concentrations at specific wavelengths along its 0.125m measurement path. Internally-stored calibration data are used to convert these absorption values to a mole concentration for each gas. Measurements are made at 20 Hz frequency.

Abbreviation: leeds-licor-7500
Keywords: CO2, H2O, water vapour, carbon dioxide
