Established in 1995, Tech Equipment Sales Inc. has been in the refurbished tech business for 25 years. Beginning in the Philadelphia area, Tech Equipment specialized in re-purposing liquidated electronics from institutions like the University of Pennsylvania and Lockheed Martin. Our company evolved into refurbishing/reselling electronics and reloading fired brass. This led us to where we are today. We've been selling medical grade electrocardiogram machines to certified professionals for over five years. We're proud to be trusted by doctors and physicians all over the world for their electrocardiogram machine needs.
