Specifications include, but are not limited to: Analytical System Electrochemical Sensor (Fuel Cell) Select sensor, manufactured to Intoximeters exacting specifications for accuracy, repeatability and long life. Measurement Range 0.000 to 0.440 g/210L The off the shelf instrument is designed to offer a range of results that our customers commonly encounter when performing breath alcohol testing. Custom ranges, and results reported in most units of measure are available upon request. Accuracy and Precision Highly accurate and precise evidential grade results Intoximeters fuel cell based instruments set the industry standard for accuracy and precision. These precise and linear devices offer consistent output that results in evidentiary grade analysis. Sensor Selectivity Highly specific for alcohol Fuel Cell sensors are sought after for their specificity to alcohol. Sampling Method Flow, Volume, Breath Drop Instruments running the standard software require a consistent flow, a minimum volume and then a drop in flow before sampling a deep lung breath. Alternate sample capture algorithms are available in customized programs.
