(KMOV) -- Several police departments throughout St. Louis County are now armed with a new device that could help prosecute drunk drivers. It’s what’s being called the “Next Generation Breathalyzer”.

“The good part about the new instruments, is that it uses two different devices, one to measure the quality of the breath sample and one to measure the quantity of the breath sample,” said Officer Kurt Roettering with the Des Peres Department of Public Safety.

Officials say chemicals that can cause inaccurate readings aren’t picked up by the new breathalyzer.

“This new instrument is ethanol only,” said Roettering. “It detects ethanol and gives you a measurement of ethanol only. So that takes the chances of false readings away.”

The digital device, reminds officers of the series of steps required before a subject can blow.

“It prompts them through everything they need to do, and makes sure they have done everything they are suppose to do as far as observing the person, checking certain things,” said Officer Terry Cordia with the Chesterfield Police Department.

As of now, Kirkwood, Town and Country, Des Peres, Chesterfield and the St. Louis County Police Department will be using the new breathalyzer starting on March 1.
