A portable instrument (TRASOR: TRAnsit-time SOil Respirometer) dedicated to the measurement of the soil respiration in situ was assembled using a commercial infrared gas analyzer and a data logger. A closed system, TRASOR has a principle of operation resembling that of transit time leaf porometers, widely used in the 80s and early 90s. Transients may be monitored in real time in a graphical form, allowing for immediate detection of system malfunction or non-linearity of data.

Abstract
A portable instrument (TRASOR: TRAnsit-time SOil Respirometer) dedicated to the measurement of the soil respiration in situ was assembled using a commercial infrared gas analyzer and a data logger. A closed system, TRASOR has a principle of operation resembling that of transit time leaf porometers, widely used in the 80s and early 90s. Transients may be monitored in real time in a graphical form, allowing for immediate detection of system malfunction or non-linearity of data. The comparisons made showed that TRASORs respiration rates were comparable to those measured with commercial systems.
