Evaluation of commercial breath-alcohol simulators: further studies.
Exemplars of current commercial breath-alcohol simulators were studied to ascertain their suitability for control tests and as calibrators in breath-alcohol analysis. Temperature, effluent volumes and pressures, effluent-alcohol concentration, and alcohol depletion were measured for simulators coupled with various current alcohol analyzers. Effluent recirculation was found to extend the number of acceptable control test cycles by 3.2 x over nonrecirculation. We found substantial improvements in current commercial simulators and in their performance over those evaluated in 1979.
