Building on almost 30 years experience with alcohol fuel cell sensors

We manufacture alcohol calibration standards for the regular servicing of breath analysers. They can be supplied with analyses traceable to UKAS national primary standards (analysed by LGC Limited) - we are now the sole manufacturer of UKAS traceable standards for the servicing of evidential breath analysers, our products being used to maintain and audit evidential breath alcohol equipment throughout the United Kingdom and the Irish Republic.

Dry Alcohol Standards

Conventional liquid calibration standards for breath analysers are more than 99% water. For customers further afield where the total weight of a shipment would be excessive, we have developed an 'instant' version to which 500 ml of water is added to generate the calibration standard.

DAS can be supplied to any value, have a recommended shelf life of 1 year, and their lids are fitted with a security seal. They cannot be supplied certified.
