Abstract
Calibration and accuracy check systems for a chemical sniffer, such as a breath alcohol tester, which utilize the dispensing of droplets with determinable concentration of alcohol and/or other liquids in a determinable number either directly to a reaction chamber, or into a carrier gas which can be sampled. The systems generally provide for accurate sample concentration being provided to the breath tester while also providing for a simplified system which can be easier to move, and require less operational complexity, than prior wet or dry calibrating systems.
