Advanced Photonix, Inc. Receives World's First UL Mark Certification for Terahertz System

ANN ARBOR, Mich. — Advanced Photonix® (NYSE MKT: API), the leading supplier of terahertz systems to industry, announced today that it has received full certification from Underwriters Laboratory (UL) to use the UL Listing Mark for the T-Gauge® system. Along with the UL Listing the Company also received an internationally recognized CB Test Certificate. This is the first and only Terahertz system in the world to receive the UL Listing Mark.

The newest product in the API T-Ray® family, the T-Gauge® system, is robust, fast and easy to implement. The T-Gauge system can be used in industrial settings for online process and quality control. The system is capable of measuring physical properties of products such as multi-layer thickness, basis weight, moisture content, subsurface defect detection, delamination detection. Our innovative instruments are non-destructive, non-contact, safe and are designed to increase productivity, accuracy and reduce material usage.

"This is a major milestone for API and our customers," said API CEO Richard Kurtz. "With the UL Mark we are raising the bar on industrial terahertz systems to a new level. This instills confidence in the durability, reliability and safety of our T-Gauge system. Our CE approval is still pending, but we expect to receive that approval before the end of this calendar year. We look forward to greater acceptance of our nondestructive quality control systems through the strength of our UL certification."
