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.
