Legacy Products

Alpha Moisture Systems moisture measurement instruments are specified worldwide in many test methods and protocols, usually identifying a specific model. Unfortunately, these test methods may not be reviewed frequently and updating complex documentation to take advantage of new products from Alpha Moisture Systems can take several years. To satisfy the requirements of these existing test methods and protocols, we continue to manufacture earlier generation ‘Legacy’ Portable Dewpoint Meters, Hygrometers, Transmitters, Dew Meters and Dewpoint Analysers for as long as practically and commercially viable. Due to lower production volumes and component scarcity, the latest generation instruments are usually less expensive.

Our Technical Sales Team can assist you in transitioning to the latest generation of dewpoint hygrometers and transmitters and explain the new features and enhancements.

We offer repair and dewpoint calibration of Legacy instruments to National and International Humidity standards; a 12-month warranty covers repairs.

Do not hesitate to contact us with details of your repair or calibration requirements or for guidance on selecting a new generation instrument.
