gas analysis (IRGA) and found them to be highly correlated, with r 2 =0.95. The use of IRGA provides the potential for automation in a system due to the electronic output. Bowling et al. (2001) described a system using a pneumatically driven piston to inject sample air, which gave consistency and high accuracy (a coefficient of variance of 0.05%). This and similar systems afford accurate measurements by incorporating complex mechanics, but can be expensive and time intensive to maintain. An emphasis was placed on simplicity and cost effectiveness, while still allowing for some degree of automation and instantaneous measurement results.
