Building Protection and Mail Screening

Pathogens are a problem. In the biodefense and mail screening industries, attacks can occur without warning. It is important to maintain adequate protection to prevent events like the 2001 Anthrax attacks and the recent mail threats targeted at high profile political figures. PathSensors provides industry-leading pathogen detection to ensure building protection and your safety and security. 

Technology designed to keep you safe.

Trusted and tested by the U.S. Department of Defense


Threat detection across industries

Incorporating CANARY® technology, our products provide rapid, sensitive and specific identification of biothreat agents (bacteria, viruses, and toxins) from aerosol samples. Our flagship product, the BioFlash, can be integrated into a suite of CBRNE protection solutions, or used as a standalone device in building security and mail screening applications.

In addition to the standalone BioFlash device, we also offer a MailGuard System that includes a negative pressure hood for optimized threat containment. Are you interested in improving your building monitoring or mail screening capabilities? Take a look at our options below.
