DUI Metrology Dictionary
Crowns will say that if a police officer says the instrument is an 8000C then it is an 8000C. In reality the two instruments evaluated by the CFS and RCMP for the ATC all those years ago, were probably very different from what is coming off the line today. Does the uniqueness of the calibration curve on each individual instrument render every instrument different from the first two? The Intoxilyzer 8000C is manufactured by CMI, Inc. in Owensboro, Kentucky. The manufacturer tightly controls sales. Instruments are not sold to lawyers or experts in private practice for inspection or independent evaluation or experiments as to malfunction.
