SONOWALL 70

Advantages at a glance:

  • High performance  & compact design
  • Flip-screen-feature simplifies usage
  • Robust aluminum casing, IP 67

For various thickness applications:

  • Corrosion testing
  • Through-coat testing
  • Precision measurement

The new thickness gauge is perfectly suited for various ultrasonic thickness applications. The robust aluminium casing with IP 67, a light weight of only 990g and high resolution anti-glare 5-inch graphic display make the SONOWALL 70 the ideal thickness gage in harsh test environments.

Intuitive operation

In addition to high performance, the focus during the development for this new thickness gage was on intuitive handling and clear display of measurement results. An intuitive user interface, clearly structured menu, and the presentation of all menu items in full text simplify and accelerate the set-up and opertation of the device, and reduce the risk of incorrect settings.

All relevant measurement values and device settings such as wall thickness, A- or B-Scan, and individually adjustable test parameters are apparent at a glance on the large display screen (800×489).

Thanks to the innovative flip-screen technology, the device can be used with either hand for convenient working.

Intelligent probe identification

SONOWALL 70 is the first thickness gage in the market with intelligence probe identification. The extended probe management allows probe-specific information, such as DAC-curves, delay lines and serial numbers, to be saved directly in the probe.

In addition to various thickness applications, the device can be upgraded to a full-function flaw detector.
