6497  Tritex NDT  says its sophisticated triple echo ultrasonic thickness gauges are  robust, accurate and easy to use. The Multigauge 5500 model is supplied  with a belt clip for hands-free use when climbing on staging, ladders or  scaffolding for bridge surveys. The easy to use keypad allows operator  interface whilst the bright LED display can be used in an array of light  conditions. All probes have an intelligent probe recognition (IPR) tool  that automatically adjusts settings in the gauge at the same time as  transmitting recognition data. The unit also comes with an automatic  measurement verification system (AMVS) that ensures true measurements  are displayed, even on heavily corroded metals. Another feature reduces  preparation time as it eliminates the need to remove surface coatings so  just the metal is measured.
