Increased Productivity

Temperature operating range: You can take full advantage of all the power of TOPAZ16 from -10 to 45 degrees Celsius (14 to 113 degrees Fahrenheit). Add the optional fan kit and TOPAZ16 delivers in environments up to 53 degrees Celsius (127 degrees Fahrenheit). TOPAZ16 is built to meet your specific needs no matter how harsh the environment.

264mm/10.4in high-resolution multi-touch display: TOPAZ16 features a very wide, highly responsive multi-touch screen that not only offers high-resolution but also one of the largest display-to-instrument footprint ratios. With TOPAZ16, you can see more data more clearly whether inside or outdoors.

High signal quality: With digitizing up to 800% and 16-bit amplitude resolution, TOPAZ16 provides the signal quality you need with less chance of saturation.

Multi-probe and multi-group support: The TOPAZ16 makes weld inspections simple with the optional probe splitter accessory.

Unmatched Value

TOPAZ16 delivers big value in a small footprint. From preparation to reporting, TOPAZ16 is the complete solution. This fully integrated and simplified approach can reduce the amount of equipment needed to perform an inspection.

Fully Integrated Inspection Process

TOPAZ16 can handle all steps in an inspection process, helping to lower costs thanks to:

Preparation: Specimen editor and focal law calculator helps make setups simple.

Acquisition: TOPAZ16 has the features that deliver a highly efficient data acquisition process.

Analysis: Full suite of basic and advanced tools onboard for a more efficient and effective analysis.

Reporting: TOPAZ16 is ready to print standard or custom reports in a touch.

Seamless Setup with Eddyfi Technologies' Scanners and Probes

Getting started with TOPAZ16 couldn’t be easier. When any Eddyfi Technologies' scanner such as the award-winning NDT PaintBrush, Weld Crawler, or probe is connected, TOPAZ16 can automatically recognize and preconfigure the inspection sequence accordingly, saving valuable time. More flexibility to meet your needs:

  • Multiple scanning configurations: sector, linear, and compound
  • One dedicated UT channel: a separate conventional UT channel offers 200v pulser and works in P/E or P/C configurations for TOFD examinations
  • Fast and safe data transfer: TOPAZ16 features an internal solid-state drive (SSD) for quick, reliable data transfer and storage during operation
  • Numerous connectivity options: TOPAZ16 has the connectivity options you need and includes one USB 3.0 port (delivering 10x speed improvement vs. USB 2.0), two USB 2.0 ports, Gigabyte LAN, HDMI, plus one UT channel and a PA UT connector
  • IPEX connector option available.
