PRISM: The Solution to Calibration
When choosing to invest in a breathalyzer, accuracy is the most important factor to consider. However, all breathalyzers lose accuracy over time (usually in one year or less), and the current fix for this loss in accuracy is manual re-calibration.
Manual re-calibration is a flawed process, because the actual residue buildup and functional degradation inside the sensor cavity is not addressed at all; re-calibration simply "re-teaches" the device to show better results with the now-degraded sensor. After several re-calibrations, sometimes after even the first one, the sensor may have degraded too far, at which point re-calibration cannot even be performed and the device is now just a paperweight.
These flaws are all completely erased by the introduction of PRISM Technology and its user-replaceable sensor modules. Replacement is quick and easy, and replacing the module is the only way to restore true "day one" accuracy to your device.
