Where it is used
Typical tasks
- Pipe corrosion near walls, supports and in tight spaces
- Hot surfaces up to +500 °C
- Rounds with 27MG, 45MG and 39DL PLUS gauges
Overview
The D791 is an Olympus (now Evident) dual element ultrasonic transducer for thickness gauges with a right-angle connector. It matches the D790 in specifications, but the cable exits sideways, which is handier in tight spaces.
