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. PRISM = Pre-calibrated Replaceable Intelligent Sensor Module Sensor Panel Access Once the sensor becomes degraded resulting in a loss of accuracy, you can literally remove and discard the existing module containing the sensor and replace it with a newly manufactured, pre-calibrated sensor module.
