Biological Aerosol Detector
The Tac-7® biological aerosol detector measures the biofluorescence and diffractive scattering produced by aerosol particles as they pass through an intense ultraviolet beam. It is used to monitor environmental particulates and classify them as being of either biological or non-biological origin, and to alarm if there is a sudden increase in the bio-aerosol level. It was developed by CBRN International for homeland security, public health and military applications.
Electric power consumption is less than 7 watts, allowing operation from either a small solar panel or for more than 24 hours on its swappable rechargeable battery. Multiple units may be monitored remotely using Windows-based software provided at no charge. The software can also be used to modify operating characteristics or alarm levels as needed or desired. All data is also automatically stored onboard on a removable solid state memory chip with a five-year capacity.

Ideal for Use in the Field
Lightweight and compact, the Tac-7 has a wide operating temperature range and can operate for 24 hours or more on rechargeable battery.
The Tac-7 can communicate with a computer or air sampler using an RS-232 connection or wirelessly with Bluetooth transmitters and receivers.
Long-Term Data Storage
Tac-7 is equipped with an onboard removable SD-type data card that can store more than five years of aerosol data.
