The purity of the ethanol used shall be compared with the National Institute of standards and Technology (NIST) Standard Reference Material for ethanol.

Police get new tool to convict drunk drivers

The 12V500 Duplex Alcohol Simulator retails for $1,359 and delivers a known and precise amount of alcohol to the analyzer before each breath test.

That process lets police know the machine is working properly, said Greater Sudbury Police Const. John Coluzzi, and ensures any blood-alcohol readings it takes are as precise as possible.

With the rise of personal breathalyzer use, calibration of more accurate breath tests still critically important

We have encountered students who have used [personal breathalyzers] thinking they were sober, trying to be responsible, and getting a DUI shortly thereafter,” Letendre said."

Letendre says not all personal breathalyzers are as accurate as the readings we found in our test with BackTrack and warns about a ‘false sense of security’ for drivers who use them.
