What is Pre-Calibrated Replaceable sensor module? 
One of the main problems with using breathalyzers in critical applications is that the alcohol sensor, no matter what type, requires periodic re-calibration. Unfortunately, the recalibration process requires that the breathalyzer be physically mailed or taken to a  professional service center, at which point the device must be evaluated and proper steps must be taken for calibration with an expensive simulator system. 
The process is costly for both consumer and service center, and the delay of processing and shipping back-and-forth can be quite a loss. The Pre-Calibrated Replaceable Alcohol Sensor Module can eliminate the delays and complications of re-calibration by allowing you to simply "snap out" an old module and "snap in" a new module. 
This way, you can get back to reliable, accurate testing in a matter of seconds!
