What is Calibration?
All breathalyzers indicate BAC (Breath Alcohol Concentration) based on the information stored in the sensor's memory. Exact values of certain specific BAC data are stored so that the sensor can provide the most accurate readings.

Over time, however, these stored values lose accuracy as more tests are conducted. The stored sensor values deteriorate over time with continuous testing and external/ environmental effects. All breathalyzers must be recalibrated to refresh the sensor values and to allow the breathalyzer to obtain accurate readings.

How often does my breathalyzer require re-calibration?
It varies depending on the specific breathalyzer model and its usage but it is recommended that breathalyzers be calibrated every 200~300 tests or 4~12 months.

Is there a charge for re-calibration?
Yes, the fee is $35.00, which includes return shipping to you. All breathalyzers (except the AlcoMate Premium, AlcoMate Prestige and AlcoMate Plus) require periodic re-calibration, which is not covered under any warranty. Only ALCOMATE and ALCOSCAN brand breathalyzers are covered (any other product may be returned without service).

FOR RE-CALIBRATION,
SHIP YOUR PRODUCT TO:

AK Solutions USA LLC
21 Grand Ave., Suite 102
Palisades Park, NJ 07650, U.S.A

along with a $35.00 check or money order
payable to AK Solutions USA, LLC.

The $35.00 fee includes return shipping to you.
Please include a complete return shipping address
and a daytime contact telephone number.

You may send your device in its protective case or pouch,
but please DO NOT send mouthpieces, user's manuals or loose handstraps
unless you are returning your product for repair or replacement.

How long does it take to return a breathalyzer sent in for re-calibration?
Generally, it takes 2 to 3 weeks for receiving, processing, calibration and return.

What are "Pre-Calibrated Modules"?
Pre-Calibrated Sensor Modules eliminate the need for re-calibration. Please refer to our Pre-Calibrated Sensor Modules page for more information.

What is "self-calibration"?
User "self-calibration" will not restore the sensor to precise values, but it may improve general sensor accuracy. The sensor is sensitive to temperature, humidity, and air quality and the sensor readings may be affected. Self-calibration does not reliably maintain accuracy over a long period, which is why the "feature" is limited to lower-quality devices.
