The new CONT.AIR is a handheld particle counter designed for cleanroom monitoring, air quality control, industrial applications, occupational health and safety, and scientific research.
This instrument is used to detect, count and size the aerosol particles present in the air. Unlike a microbial air sampler, which gives the number and the type of micro-organism captured on the agar plate, the particle counter gives the number and the size of the non-viable particles present in the air. These particles can be the transport agents for viable ones (micro-organisms).
The instrument detects particles in a range from 0.3 to 25 µm across 6 pre-set channels (generally 0.3, 0.5, 1.0, 2.5, 5.0, 10.0 µm). It operates at a flow rate of 0.1 CFM (2.83 l/min). It provides data output both in standard cleanroom formats and in mass concentration (µg/m³).
The firmware is user friendly, and the presence of a pen facilitates the use of the touchscreen keyboard. The possibility to integrate the instrument with temperature and relative humidity probes generates more detailed environmental assessments. Light, ergonomic and easy to use as a portable device. The instrument is patented.
