Universal Detection Technology (fka UNDT)

[Zorro]

They are not a reseller. They hold the license on the tech which they have used to develop the product they are selling. There is no middleman. UNDT just does not manufacture their own devices:

Universal Detection Technology (UNDT) has licensed a spore detection technology from NASA's Jet Propulsion Laboratory (JPL) and has developed a first of its kind real-time continuous detection device capable of identifying abnormal levels of bacterial spores in the air, an indication of a possible anthrax attack. The Company constantly seeks to license new technologies based on which it can transform cutting edge science into tangible and everyday products. Additionally, the Company offers its expert advice to customers with regards to a variety of subjects including post and pre incident planning, bio-terror detection for large events, and drafting customized security plans for customers interested in taking a proactive approach against bio-terrorism.
