What is a "Pre-Calibrated & Field Replaceable Sensor Module"?
Like any other analytical instrument, breathalyzers require periodic calibration to ensure their accuracy. Our pre-calibrated and field replaceable sensor module is a patent pending technology built in our new generation of breathalyzers that has resolved all problems and complications arising from otherwise existing calibration processes.
Calibration of a breathalyzer is a compensation for deviations in a sensor due to contamination and aging. The calibration process does not remove contamination but it makes up for any deviation of BAC step thresholds levels from previously calibrated levels.
Our experience has shown that multiple calibrations of the same semiconductor sensor eventually leads to failure and sensor replacement is required. This has been the main problem with using breathalyzers in critical applications. Unfortunately, the calibration 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 breath alcohol simulator system. The process is costly for both consumer and the service center, not to mention the delays involved in processing and shipping back-and-forth that can be quite a loss.
The pre calibrated and field replaceable sensor module has eliminated delays and complications of a calibration process by allowing users to simply "snap out" an old sensor module and "snap in" a new module. Restoring accuracy to AlcoScan AL7000 takes a matter of seconds and it only costs $29.95 for each sensor module. This will restore the unit accuracy back to its condition as new from the factory.
