How frequently should the Intoxilyzer 9000 be calibrated?

The frequency of calibration for the Intoxilyzer 9000 is crucial to ensure accurate and reliable breath alcohol concentration readings. It is required to be calibrated at least once every 30 days or after any maintenance. This regular calibration helps to account for any drift in the machine's measurements over time or due to any adjustments or repairs that may have been made. Keeping a consistent calibration schedule minimizes the risk of inaccurate results, which could impact legal proceedings and public safety.

While calibrating every week, annually, or before each test might seem adequate in some contexts, these frequencies do not align with the established guidelines for the Intoxilyzer 9000. Calibration every 30 days strikes a balance between maintaining accuracy and operational efficiency, ensuring that the equipment is working correctly without requiring unnecessary frequent calibration checks.
