CMC-KUHNKE Dome Reversal Tester

The DRT-3000DG Buckle Tester is a semi-automated buckle tester designed to determine the exact pressure at which the bottom dome of a can begins to buckle. 


Developed by Quality by Vision, our specialist vision inspection brand, the Dome Reversal Tester (DRT) is a multi-testing can measurement system 

All-in-one can measurement system  

Our versatile can measurement system is available in four measurement modes, all with graphical data representation: 

  • Buckle test  
  • Can height with fixed pressure levels 
  • Flex mode: buckle test and can height test in 0.05bar increments – ideal for R&D laboratories 
  • Can height permanent test – can height test only – with fixed pressure levels. 

The Dome Reversal Tester is also available for two-piece food cans…get in touch for more information.  

A robust can measurement system

The solid structure and design of our can measurement system is built to withstand the rigors of the plant environment. So you can rely upon the long-term  accuracy of our beverage can testing technology, time and time again.  

Graphical beverage can test data options

You’ll quickly get to grips with your can buckling data using the DRT can measurement system. The color icons and simple menus provide easy navigation through the functions of the gauge – saving you time and fuss.  

Use our graphical user interface to inspect your results on the color touch screen digital display. Then transmit them to a computer via the RS232 computer interface or analyze them through CMC-KUHNKE’s Display IV graphical evaluation Software. 

‘Quick fill’ can measurement system  

The ‘quick fill’ feature of our beverage can test machine rapidly increases the pressure to a set amount. Once it’s ready at the starting pressure, you reduce the fill rate to optimize its accuracy. 

Can buckling product portfolio 

Across the Industrial Physics portfolio we have plenty of devices that are similar in function to the DRT-3000DG Buckle Tester. 

For example, there’s the CMC KUHNKE Front End Station – an innovative and accurate can gauge that delivers fast measurements of trimmed can products.   

Also take a look at the BES-3000, it’s an operator-independent automatic gauge for two-piece beverage can testing. The hands-free design eliminates measurement errors caused by operator interference. 

Our can buckling testing experience measures up!

We’re always pleased to share the knowledge we’ve gained over almost 100 years of working with metal packaging.  

In the knowledgebase section of our website you’ll find lots of blogs about can inspection. For example, there’s this one on how to measure a double seam, or this piece which delves into different types of can inspection and how they’re achieved.  

Then, if even a fraction as obsessed with metal packaging as we are…we think you’ll enjoy reading our popular history of a can timeline!

Success Stories

The problem

Some paint manufacturers have to undertake so many different types of tests that it’s hard to stay on top of the demands of their industry and the changing technologies that can best support them.

The solution

This was the case for our valued customer. They needed the equipment, skills, experience, and collaboration of a genuine partner. One offering personalized support and guidance identifying the correct inspection solution for each situation. We are always delighted to help.

The outcome

Daniel Marschall, President of Marschall Labs, said:


“The professionals at Industrial Physics took the time to understand the specific testing equipment needs of our lab. I can’t say enough about the excellent customer service and support they provide.”
