General description

The MAS-100 NT® Ex microbial air monitoring systems are high performance, portable, battery operated instrument which are based on the principle of the Andersen air sampler. These compact yet sophisticated devices are the preferred choice for those demanding the highest quality in microbial air monitoring. An ambient amount of air is aspirated through a 300-hole perforated lid and impacted onto the surface of growth media in standard 90-100 mm Petri dishes or 55-60 mm contact plates. Microorganisms are impacted onto the agar and, after an appropriate incubation period, the colonies are counted. The system measures the airflow and regulates it to a constant value of 100 standard liters/min A Standard Liter Per Minute (SLPM) is adjusted to a specific environmental temperature and pressure, this ensure the amount of air sampled is always the same and independent of environmental conditions. These systems have the highest airflow accuracy of ±2.5%, compared to others that can be as high as ±10%. The integrated flow sensor allows the user to freely interchange the perforated lids without affecting the accuracy or the calibration of the unit. The MAS-100 NT® Ex is powered by a Lithium ion rechargeable battery with an intelligent charging program that assures long battery life without routine discharging.


The MAS-100 NT® Ex air sampler is used for microbial monitoring of ambient air in explosion hazard areas. Microbial air sampling devices are extensively used in Pharmaceutical and Personal care industries as well as Food, Beverage and Environmental applications.


Includes hard carrying case, battery, 300-hole perforated lid, dust cover, main charger, USB cable, 3 mm allen key, USB stick with all documentation
