The PRISM (Pre-calibrated Replaceable Intelligent Sensor Module) is the core technology that sets the AlcoMate Premium AL7000 apart from traditional breathalyzers. This component allows for instantaneous, field-level calibration by simply swapping the old sensor with a fresh one. This is a critical advantage for Abbott Toxicology clients in the maritime, corporate, and law enforcement sectors, as it eliminates the 2-4 week delay typically required for mail-in laboratory calibration. For optimal accuracy and to maintain DOT compliance, the manufacturer recommends replacing this module every 200 tests or at least once per year.
