A report from the Colorado Department of Public Health and Environment, stated problems with calibration affect 33 breathalyzer tests in Weld County, Colorado. The report indicates the device did not have the proper tolerance target entered during the initial certification process, and officers did not identify unacceptable calibration results on those tests, which would have aborted the tests due to error.
The report further indicated that the machine's manufacturer, CMI Inc., told the department on May 9 that a DUI attorney contacted them about a test that indicated an out-of-range temperature on a peripheral instrument, called a Guth 12V500, that is also used to check the calibration of the Intoxilyzer 9000.As a result, every result from the Guth 12V500s in use in Colorado was audited. The Intox 9000 has just been selected as Georgia's new breath testing device, so any reports of inaccurate testing in other states could be important information for your Georgia DUI case.
