FOxSense™
The FOxSense™ fiber-optic oxygen sensor product line offers a unique fully all optical, single-point, and multi-point, oxygen monitoring solution with built-in temperature and/or pressure compensation, for many applications in biomedicine, pharmaceuticals, chemical and oil industries, environmental monitoring, aerospace, and defense. The FOxSense™ system uses ROI’s proprietary frequency domain “phase-locked” multi-channel fluorescence lifetime measurement technology for the fast accurate and reliable measurements of the fluorescent lifetime state of fiber-optic O2, T&P sensing elements.
