The Q-Box SR1LP Soil Respiration Package provides the user with all of the materials required to measure soil respiration in situ.  Short term spot measurements in the field are possible with the battery pack.  Soil samples can also be asessed back in the lab when placed in a flow-through chamber.

Soil respiration is measured as the rate of CO2 accumulation by the Q-S151 CO2 Analyzer.   In addition to soil respiration Q-Box SR1LP package allows measurements of soil temperature with the S132 temperature probe and water loss from the soil with the S161 Temperature/Relative Humidity sensor.  Soil moisture is measured with the S135 Soil Moisture Sensor.  The flow through the system is monitored by the Q-G266 Flow Monitor.  The Analog signals from all of the sensors and analyzers are converted to digital signals via two integrated LabQuest mini interfaces (6 channels).  Data is displayed, recorded and manipulated on a PC or Macintosh computer using Logger Pro software.

There are many other potential applications for Q-Box SR1LP package both in open flow and closed gas exchange systems.  For example, it can be used to measure CO2 exchange from any organism or sample maintained in a flow-through chamber.  In addition, it can be used to examine respiration or fermentation in aqueous suspensions when air or N2 is bubbled through the suspension and the outflow gas is analyzed using the CO2 Analyzer.  Provided that CO2 production rates are in the correct range, the package can be used to measure CO2 production of virtually any biological system.
