ANN ARBOR (WWJ) — Advanced Photonix (NYSE MKT: API), the leading supplier of terahertz systems to industry, announced that it has sold two new T-Gauge terahertz sensor systems.

The first sale is a spare or backup system for an existing T-Gauge system used in a critical manufacturing process overseas. The second system will be deployed on an industrial manufacturing line to provide 100 percent inspection of roofing materials for quality control. This inspection system is expected to be the first in a number of systems deployed to this customer.

The ability of terahertz energy to penetrate non-conducting materials — but without the damaging, ionizing punch of X-rays — allows inspection of solid and liquid products after packaging. The wide frequency content and high precision of the T-Gauge system provides sensitivity to both physical and chemical changes in the product. Measurement of thickness, density, and certain material properties can be used to monitor the quality of the product being produced.
