SDT Ultrasonic Multi‑Transmitter

The SDT Ultrasonic Multi‑Transmitter (Model SDT 170 S) is the entry-level handset in the SDT 170 platform. It features an internal airborne ultrasonic sensor paired with a user‑friendly, ergonomic aluminium body protected by anti‑shock insulation. The handheld unit is operated via an eight‑key touchpad and displays measurements on a segmented analog bar graph. It excels in detecting compressed air and vacuum leaks, inspecting electrical issues such as arcing or corona, steam‑trap functionality, and general mechanical inspections where trending and complex data logging aren’t required.
