AMA - Sampling Units
AMA Instruments offers a wide range of portable and automated sampling units performing high precision air and gas sampling. The sampling units are primarily used for indoor air monitoring, occupational health and safety monitoring or observation of legally required limits in industry or environment. While sampling an exactly defined air or gas volume will be drawn through special adsorption tubes, filters or washing bottles for subsequent laboratory analysis.
All sampling units feature a thermal flow sensor, which allows for precise measurement of air and gas volumes referenced to standard operating conditions irrespective of pressure and temperature fluctuations.
An integrated Mass Flow Controller (MFC) provides for automated flow rate control and precise air sampling even in case of varying back pressures, e.g. caused by gradually clogging of adsorption tubes in case of particle loaded air samples or by differing liquid levels of washing bottles.
AMA sampling units allow for volume or time-based programming and can be either line or battery powered. A splash-proof membrane keypad with integrated LCD display provides easy field set-up and operation. Due to the weather-proof and rugged design of the housing, our sampling units can be used even under harsh conditions.
