GLEN ROCK, NJ — PBI-Dansensor has upgraded its leak detection systems for Modified Atmosphere Packaging (MAP) with two new systems, the company announced recently.

The new LeakMatic II and LeakPointer II now utilize a state-of-the-art optical CO2 sensor to detect package leaks, the company said. The new optical sensor is faster and more responsive to detecting even trace amounts of CO2.

The new optical sensor delivers many benefits to the packer/processer:

• Not sensitive to the elevated CO2 levels often found in a MAP food production environment.

• Ready to use in one minute.

• Works in tandem with a new, advanced leak-testing algorithm that ensures accuracy of actual leaks in the MAP product.

Both the LeakMatic II and LeakPointer II use a non-destructive testing technique that spots leaks without destroying packages, according to the company. Both products use a vacuum chamber and an automatic test cycle to detect CO2 leaks. The LeakMatic II is a fully automated, in-line leak detector designed for medium and large applications. PBI-Dansensor said it ensures the seal integrity of individual packages or entire boxes of MAP products at a speed of up to 4 cycles per minute.

The LeakPointer II is for use in an off-line setting designed for smaller applications of leak detection. Unlike water bath detectors, the Leak Pointer II eliminate the risk of cross contamination and operator subjectivity. Individual test programs are created for each product tested and the full test cycle takes 15-30 seconds depending on the product set up, the company said.

"PBI-Dansensor invented CO2-based leak detection around 20 years ago - a method that is a fast and reliable way of finding leaks without the mess of water," said Karsten Kejlhof, sales and marketing director. "We have unrivalled experience in the field and have now advanced the technology even further.

"Leak detection needs a technology that is fast and extremely accurate," Kejlhof added. "The new system achieves these goals, as well as being versatile and user-friendly."
