The BaCTraCK select s50 Breathalyzer is calibrated during
manufacture using advanced alcohol simulation equipment.
Known alcohol concentrations are passed through the sensor
to set baseline values for testing. During testing, the unit
compares users’ breath samples to these baseline values.
The accuracy of breath alcohol testers can fluctuate after six to
twelve months of normal use, depending on the number of tests
performed and operating conditions.
If this product is providing inconsistent test results, is not provid-
ing any test results, or provides unusually high or low test results,
the product should be recalibrated by a trained professional.
The product should be recalibrated at least every six to twelve
months depending on frequency of use and operating condi-
tions. we recommend sending the unit in for calibration after
200 tests have been performed, or every 6 to 12 months if
less than 200 tests have been performed. If the product is used
every day, it may need to be recalibrated as frequently as every
month.
