The QSArray is Built, Patented & Proven

Executive Summary QuadraScan Technologies has developed a patented* technology that targets a significant quality, production and manufacturing related problem, leak detection and location. The Problem detection of leaks and/or build variation is an integral part of Quality Control (QC). However, OEM’s have traditionally relied on subjective test processes utilizing water, which is potentially damaging, costly, and raise environmental and plant safety issues. The Solution, the QSArray V 2 identifies and locates leak points and/or build variation in a non-destructive fashion. Our technology utilizes ultrasound to test the “sealed effectiveness” of closed compartments. This technology provides an accurate, repeatable, and unbiased data instrument empowering the manufacturer to adopt a quantitative scale of measurement The QSArray is Built, Patented & Proven * patent #

What The QSArray Does - The Benefit The QSArray utilizes ultrasound energy to test the “sealed effectiveness” of a vehicle. The QSArray will provide an immediate return on investment by; –Enhancing the plants quality control process –Providing quantitative data regarding variations during production –Creating an archived UltraSound “Fingerprint” –Opening valuable plant floor space. –Eliminating water test labor and maintenance costs. –Creating a positive impact on environmental and safety standards by eliminating water and chemicals.
