MAS‑100 NT®

Volume and mass flow measurement

The MAS‑100 NT® is the world’s best-selling air sampler, designed to monitor air microbiology in cleanrooms and hygienically ultra-sensitive areas. Its high recovery rate is based on the Andersen impaction principle. An integrated airflow sensor compensates for differences in pressure and temperature in the environment. In combination with the DA-100 NT anemometer, the MAS‑100 NT® features an automatic calibration function – for precise, independent airflow testing. The instrument also allows for the use of standard Petri dishes and special plates and is exceptionally easy to use.
