  • With 2 analog inputs, the Foxbox allows the user to connect additional instruments (e.g., water vapor or temperature measurement devices) to incorporate into the data output stream.
  • Standard in our analyzers, barometric pressure compensation eliminates errors caused by ambient pressure variation.
  • 3 year warranty


The FoxBox Respirometry System is a field portable combined oxygen and carbon dioxide analysis instrument including a variable pump and mass flow meter integrated into a compact, dustproof, waterproof case. Equally at home in the lab or the field, the FoxBox is the core of a complete respirometry system.

The FoxBox can be ordered with a rechargable Li-ion battery pack. Optional ExpeData data acquisition software allows simple analysis of respirometry data. The Foxbox Daemon translates the serial data stream into an ExpeData file.


Accessory inputs Two configurable for temperature (-5 deg C – 60 deg C, accuracy 0.2 deg C, resolution 0.001C with included thermistor probe) or voltage, 0-5V, 16 bit resolution
