  • Analog and serial (RS231-8N1) outputs
  • Internal 24 bit A/D Conversion


The FC-2 dual-channel, differential oxygen analyzer (Oxzilla) is designed to detect even the smallest oxygen concentration changes between gas streams. Capable of measuring oxygen consumption from small insects, the FC-2 is the most sensitive, highest resolution analyzer in the Sable Classic product line.

The FC-2 oxygen analyzer is suitable for the most demanding oxygen measurements applications, such as Drosophila (fruit fly) metabolic measurement and atmospheric monitoring. It consists of two highly precise, temperature-controlled oxygen analyzers operating in parallel. It can therefore also be used as a dual-absolute oxygen analyzer.

Fully computerized and auto-diagnosing, the FC-2 differential O2 analyzer features an intuitive menu-driven interface that allows quick adjustment of any operating parameter. Calibration is an effortless, single-click operation. The FC-2 is fully self-contained and requires no external software or hardware to operate or calibrate. It is equipped with both analog and digital outputs for quick and easy interfacing with any data acquisition system.  And unique to Sable analyzers, barometric pressure compensation eliminates errors caused by ambient pressure variation.

The FC-2 line has become the world standard for ultra-sensitive, ultra-high-resolution oxygen analysis in critical applications such as atmospheric physics, small-animal respirometry, polymer oxidation and other fields where only the best is good enough. It has been widely cited in leading journals, including PNAS.
