WARREN, N.J.--(BUSINESS WIRE)--July 28, 1999--

Barringer Technologies Inc. (Nasdaq: BARR, BARRW), the world's leading developer, manufacturer and marketer of trace drug and explosive detection equipment, announced today that it has received approval from the Federal Aviation Administration to proceed with Phase II development work on the Company's automated luggage explosives detection system.

The Phase II work involves a detailed engineering design for the detection system. Under the Company's agreement with the FAA, the Company completed Phase I work on the project earlier this year. The Phase II work will be based on the Company's initial design concepts and is expected to be completed by December 31, 1999. If approved, Phase III of the project would include the fabrication of a prototype unit.

Building on our core technology, which has been field tested in our basic IONSCAN product line, we believe that our automated system will process checked baggage at rates well in excess of FAA specifications. Various portions of the design have already been developed and we are confident that we can complete the design of a commercially viable system that will exceed customer performance expectations."
