Description
This device utilizes a system for creating a gas with which to calibrate breath testers. The user would fill the device with water, heat the water, add a small amount of fluid alcohol in with the distilled water, and then mix the two together. The mixture had to be 98.6 degrees – the temperature of human breath – which was then put into the passive sensor to see the result. Initially.10 solutions were used (.10 was the per se limit at the time); the bubbler may still be a.10 solution. It pumps out a sample for your handheld breath tester or Borkenstein tester.
This goes into the PAS and is a way to calibrate it.
