Where it is used
Typical tasks
- Corrosion gauging of pipes, vessels and tanks
- Measurements on hot surfaces up to +500 °C
- Rounds with 27MG, 45MG and 39DL PLUS gauges
Overview
The D790 is an Olympus (now Evident) dual element ultrasonic transducer for thickness gauges. One element transmits and the other receives, so it reliably measures remaining thickness of corroded metal and works on hot surfaces.
