Our MA-2 medium animal field-portable respirometry system produces accurate, reproducible data from animals from rats up to goats or resting humans in size, anywhere - in the lab, or in the field. It can be used in push or pull (mask) mode. It is available with an optional water vapor pressure analyzer for flow and dilution compensation without requiring scrubber chemicals. This is particularly useful when the system is used for pull-mode or mask resirometry.

The MA-2 medium animal field-portable respirometry system is normally supplied with both oxygen and carbon dioxide analyzers, and measures oxygen consumption rate, CO2 production rate, RQ, and water loss rate. Using RQ, the respiratory substrate of the test animal can be determined, allowing accurate translation of gas exchange measurements to energy equivalents, e.g. Watts, Joules/hr or calories/day.

Data acquisition is fully automatic, using our acclaimed ExpeData™ software, the product of over twenty years' experience in computerized data acquisition and analysis. Complete user control over every aspect of the system's operation is supported. Baselining can optionally be fully automated, though in field situations it is usually manually baselined or self-baselining (e.g. an animal entering and leaving a habitat or feeder voluntarily). The analysis of acquired data is uniquely flexible and can also be fully automated, if desired. The respirometry equations used in the system are state-of-the-art.

All necessary tubing and accessories are supplied with the system. Lifetime technical support by published experts in respirometry is included.
