A Rugged, Portable, Fully Integrated Field Metabolic System

The portable FMS is a fully integrated field metabolic system about the size of a briefcase. The FMS combines O2, CO2, and H2O analysis with data acquisition and subsample flow control and measurement. Whether in the lab or field, the FMS has all the versatility needed in a respirometry system without compromising accuracy.

Onboard Data Storage

Capable of onboard data logging using an internal SD card (up to 32 GB).


Accompanied by an external expansion box with eight 0-5V analog inputs to connect other devices to the FMS. The expansion box also provides eight TTL level digital outputs for external device control.

Barometric Pressure Compensation

Standard in our analyzers, barometric pressure compensation eliminates errors caused by ambient pressure variation.

Three-year warranty

Sable Systems instruments are warranted to be free of defects in material or workmanship for a period of three (3) years from date of purchase. See website for warranty policy.

Lifetime Technical Support

Our technical support team will help you overcome any challenges you may face with equipment setup as well as provide advice and assistance on future applications.

Optional Accessories

BP-R: For ultimate portability, order a rechargable Li-ion battery pack (4.8 A-H) lasting up to 6 hours run time. 

CABLE-B-BC: Cable for use with customer supplied batteries.
