Importance of Calibration:
AlcoScan AL-2500 is a breathalyzer that has
calibration function. Calibration feature allows the breathalyzer to retain its
accuracy even with thousands of tests. Other products that do not offer
calibration will lose its accuracy over time and will not give accurate
readings. Many other similar products do not offer such crucial feature. The
calibration feature of AlcoScan AL-2500 will provide
accurate readings with long-term reliability.
What is Calibration?
All breathalyzers indicate BAC (Breath Alcohol Contents) level based on the
information stored in the sensor's memory. Exact values of certain BAC levels
are stored so that the sensor can provide the most accurate readings. Over time,
however, these stored values loses accuracy as more tests are conducted. The
sensor itself and the stored sensor values deteriorate over time and with more
tests, affected by external variables. In order to restore the sensor readings
to maintain better accuracy, all breathalyzers must be recalibrated to refresh
the sensor values and to allow the breathalyzer to obtain accurate readings.
How often does the breathalyzer require Calibration?
It varies depending on the breathalyzer but it is recommended for breathalyzers to be calibrated every 200~300 tests or 4~12 months.
