Fuel Cell sensor module type breathalyzer uses replaceable sensor module. Which means you do not need to send the alcohol tester to a lab for re-calibration, instead, simply purchase a pre-calibrated replacement sensor module and replace the existing sensor module — its extremely easy to replace the sensor module, simply take out the existing one and put in the new one.

Comes with a built-in mouth piece. If you do not want to use a disposable mouthpiece, you can simply use the built in mouthpiece, just push the hook at the top of the breathalyze and the built-in mouthpiece will be ready to use. Can use up to 1,000 times before you need to replace the sensor module.
