FC-10 Oxygen Analyzer
Versatile, precise - and best value 
• Robust, low noise fuel cell technology
• Range 0-100% O2, resolution .0001%
• Scalable analog plus serial outputs
• Barometric pressure compensated
BEST PRECISION TO PRICE RATIO = BEST VALUE: The Sable Systems FC-10 is reliable, research-grade, and field-portable. The FC-10 boasts resolution and stability superior to any other single channel fuel cell based oxygen analyzer. Advantages. Sable Systems’ FC-10 equals or improves upon the noise, drift and resolution performance of heated-zirconia analyzers without their troublesome high power consumption, fragility, systematic errors, and exorbitant cost. The FC-10 is compact and light, powered by uncritical 8 - 20VDC power, requires only a minute of warm-up time, and consumes less than two watts of power.
HIGH RESOLUTION, LOW NOISE: The FC-10’s extraordinary resolution is made possible by advanced, proprietary digital signal processing techniques combined with state-of-the-art electronics. The fuel cell signal is digitized to a resolution of better than one part in four million, as is the barometric pressure. The measured oxygen concentration is continuously corrected for variations in barometric pressure, thus eliminating pressure noise and drift typical of error-prone analog computational circuitry. Meanwhile, error-checking and self-calibration routines operate continuously (five times a second!) in the background, guaranteeing the reliability of the FC-10’s data.
FUEL CELL TECHNOLOGY: Sable Systems’ fuel cell based oxygen analyzers operate at ambient temperature, eliminating bulky, power-hungry furnaces. Unlike paramagnetic sensors, the FC-10 is robust; unlike heated-zirconia sensors, it is power conserving, lightweight, immune to moisture and is not affected by volatile by-products of bacterial and animal metabolism. Uniquely, the FC-10 is completely tolerant to high concentrations of carbon dioxide, thanks to its novel, patented acidic electrolytes. Sable Systems’ successful deployment of fuel cell technology depended on three vital innovations:
Ultra-low-voltage-noise amplification and filtration Sophisticated temperature buffering of the fuel cell Temperature compensation internal to the fuel cell itself
VERSATILE INTERFACE: The FC-10 is easily interfaced to any data acquisition system or data-logger. Multiple ranges of analog outputs in concentration or partial pressure units, plus cell temperature and barometric pressure, are available from four high quality BNC connectors. This versatile output scheme eliminates offsetting/amplifying by signal conditioners, and guarantees success in interfacing the FC-10 to any voltage-based data acquisition system. The FC-10 even includes a fully research-grade voltage calibrator for setting up or calibrating analog-based data acquisition systems. The FC-10 also transmits a stream of serial data. Using any computer and a terminal program, you can continuously log pressure-compensated oxygen concentration, oxygen partial pressure, internal temperature, and barometric pressure, simultaneously - and without needing any other data acquisition system.
