CMC-KUHNKE Combination Seam Gauge (CSG) – Food

The semi-automatic Combination Seam Gauge (CSG) - Food gives you precise seam thickness and countersink depth measurements, including a 360° scan around the can.


Brought to you by CMC-KUHNKE, our metal packaging specialist brand, this powerful combination seam gauge saves you time and money with its automated, multi-measuring capability. 

Multi-measurement seam gauge

Our highly accurate combination seam gauge makes light work of the following metal packaging measurements for food cans: 

  • Seam thickness: our seam gauge measures the total width of the entire double seam once curled and completed. This also includes 360°seam thickness measurements around the can. 
  • Countersink depth: with our combination seam gauge you can instantly measure the total height of the entire double seam once curled and completed.  

Rotational seam gauge precision

The Combination Seam Gauge (CSG) – Food rotates your cans effortlessly to find the right measurement angle. You can inspect a maximum of 50 points around a can and our seam gauge will even take multiple readings at the same time.  

Time-saving seam gauge testing 

Our industry-leading seam gauge saves you time and money. It achieves this through features including automatic can rotation, multiple, simultaneous measurement capacity and automatic data transfer 

Crystal clear display   

Using the easy-to-read and operate touchscreen digital display you’ll quickly and accurately analyze the results from your combination seam gauge tests. The color display clearly shows you the test stage and can display your results in graph format. 

A seam gauge that talks your language!

A clever multi-linguist, the Combination Seam Gauge (CSG) – Food translates between English, German and Chinese.   

A combination of options

Across the Industrial Physics portfolio we have plenty of devices that are similar in function to the Combination Seam Gauge (CSG) – Food.  

For example, through CMC KUHNKE we also make a combination seam gauge that’s purpose designed for beverage cans. Plus we also manufacture a more simplistic range of manual seam gauges that offer objective, repeatable and reliable measurements for beverage, food or aerosol cans. 

Seam gauge success stories

We’re always pleased to share the knowledge we’ve gained over almost 100 years of working in the beverage and canning industries. 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.

The Problem

With rising pressures on canneries and can makers to increase productivity, minimize both changeover time and unplanned stops – while ensuring higher quality closures – accurate seamer setup is vital.  

The Solution

Our customer needed a reliable instrument to speed up their seamer changeovers. We presented the ‘perfect’ solution in the Quality By Vision Clearance Gauge. It takes the guesswork out of seamer setup, improves seam integrity, increases uptime and rapidly makes changeovers. 

The Result

A spokesperson for industry-leading metal packaging  manufacturer Caniel said: “The team at Industrial Physics identified the perfect solution for our testing requirements and this has been a huge benefit for us.”
