About HDS-Messtechnik
HDS-Messtechnik (previously known as Schmetz-Messtechnik), based in Menden, is a service and trading company for ultrasonic measurement technology in preventive maintenance. The portfolio includes ultrasonic multifunction detectors (including SDT 340 and SDT 270), the HDSonic100-B ultrasonic wall thickness gauge for non-destructive, non-invasive material testing, and clamp-on flow meters for compressed air, gases, liquids and heat/energy quantities. In addition, an acoustic camera (SDT CRYSOUND) is offered for visualising compressed air leaks, gas leaks and partial discharges with PRPD mapping; it is ATEX-certified. Alongside device sales, the company carries out on-site measurements: ultrasonic leak detection in compressed air systems throughout the D/A/CH region, non-intrusive power measurement on refrigeration, air-conditioning and heating systems, as well as mechanical condition and bearing monitoring including bearing lubrication, leak testing and inspection of condensate drains. A measuring device rental service, reports and documentation of measurement data, and spare parts for SDT ultrasonic measuring devices complete the range of services.
