The ALCO XS™ is a unique new marine breath alcohol tester (breathalyser) that never requires re-calibration. ALCO XS™ saves you a fortune compared to your conventional breathalysers which need sending ashore for annual calibration or worse still, annual replacement of the whole breathalyser which is an extreme waste.

Instead, all you need to do is insert the pre-calibrated ALCO XS™ sensor cell every year (which takes a few seconds) and ALCO XS™ is ready to use, certified accurate for a further 12 months – what could be easier?

ALCO XS™ is designed specifically to meet the new “Manila Amendments” to the Standards of Training, certification and Watchkeeping (STCW) – you should check your current breathalysers to see if they have the required accuracy to meet these new limits as many don’t.
