This ultraportable BACtrack Vio BT-M2 keychain breathalyzer pairs with your smartphone via Bluetooth connectivity to rapidly estimate your BAC (blood alcohol content) and track results. ZeroLine technology estimates when your BAC will return to 0.00%.
Q: How much does it cost to recalibrate, and how long does it take?
A: All breathalyzers do require some periodic maintenance. The BACtrack Vio costs $19.99 to recalibrate. The service takes about 1.5-2 weeks.
Q: What is the life span of the product?
A: The sensor in the BACtrack Vio should be calibrated about once every 6-12 months in order to maintain its accuracy.
Q: What is the highest BAC this can read
A: The little booklet that came with it says what all the rating mean, and the highest it says is 4.00+, so I'm assuming it would read at least up to that if the booklet tells descriptions about everything under it.
