The SDT270 ultrasound detector features multiple significant innovations dedicated to the improvement of predictive maintenance programs. Manufactured by and for maintenance professionals, the SDT270’s innovations show our commitment to the production of intelligent and progressive instruments. Not only is the SDT 270 the first portable ultrasound detection device to include both a built-in temperature sensor and a laser tachometer, but it’s also the first one to feature an onboard SQL database to capture and manage survey data.
