Transonic the measure of better results. For clinicians, researchers and specialty solution developers seeking quantitative data to improve their outcomes and results, Transonic provides those measurement solutions. For four decades, the unprecedented resolutions of Transonic measurements has made the Transonic name synonymous with gold standard diagnostic and research measurement tools. Innovative Product Stream Transonic Systems Inc. was founded in 1983 by R & D scientist/engineer Cornelis J. Drost after he had invented the transit-time ultrasound flowmeter at the NYS College of Veterinary Medicine at Cornell University. As the company grew, continuing measurement innovations were the norm. Transonic measurement tools include intraoperative flowprobes for surgeons, monitors and sensors tailored for hemodialysis and critical care, and specialty sensors customized for original equipment manufacturers.
