It’s all about the DUI breathalyzer machine and BAC procedures this time. We are back talking with DUI Expert witness William Pelarenos.
He breaks it down and lays it all out for us. You’ll find out what type of breathalyzer William liked best and why.

Types of DUI Breathalyzer Machine
There are three types of DUI breathalyzer machine used by law enforcement. In Podcast Episode 035 of the Criminal Nuggets Podcast, our guest tells us all about the variety of DUI breathalyzer machine.
The PBT
The preliminary breath test breathalyzer (PBT) is typically used before the arrest. It is part of the probable cause that an officer uses to make a formal arrest.
These devices also happen to be extremely portable. They are hand held units often carried in a squad car.
The PBT is non-evidentiary in nature. That just means, that although the measurement from a PBT can be used to establish probable cause for a DUI arrest, the results are not admissible in evidence in the DUI trial of the person arrested.
PBTs are less reliable than the other machine. That is why they are non-evidentiary in nature.
The PBT must be certified every 92 days by the Illinois State Police.
Recording Breath Tester
The recording breath tester (RBT) is also a portable breathalyzer. This machine is larger than the PBT discussed above.
This machine, however, is evidentiary in nature. This means, unlike the the PBT, the recording breath tester will yield a BAC result that can be admitted in court.
The RBT must be certified every 62 days by the Illinois State Police.
The ECIR
This is the standard breathalyzer that we generally are thinking of when we imagine a police breathalyzer.
This unit is generally not portable. It is larger than the other machines described above. It is permanently located in the police station, in or near the lock-up or booking area.
The ECIR is evidentiary in nature.
The ECIR must be certified every 62 days by the Illinois State Police. Improper or non-existent certification may lead to inadmissibility of any BAC results obtained from an incorrectly calibrated or certified machine.
