For food manufacturers relying on modified atmosphere packaging (MAP), even a minor leak can spell major trouble—shortened shelf life, product spoilage, and the looming risk of costly recalls.
In response, WITT-Gasetechnik has introduced its LEAK-MASTER PRO and PRO 2 series, offering rapid, non-destructive detection of micro-leaks as small as 10 micrometres. The system is designed to ensure maximum product quality and safety with minimal operational burden, addressing concerns that stretch from the production floor to the retail shelf.
Central to the LEAK-MASTER’s performance is its advanced CO2 sensor technology. As carbon dioxide is commonly present in MAP systems, its use in leak detection represents a cost-effective alternative to more expensive trace gases like helium. During testing, a vacuum of up to 200 mbar absolute is created within the measuring chamber. This pressure differential draws CO2 from any compromised packaging. The sensors respond within seconds, making it possible to detect even the smallest of leaks without damaging the package.
This swift, automated process is entirely operator-independent, ensuring consistency, repeatability, and ease of certification. Because the test is non-destructive, any packaging that passes can go straight to market, eliminating unnecessary waste and maximizing resource efficiency.
Designed with flexibility in mind, the LEAK-MASTER PRO and PRO 2 series are available in six different chamber sizes to accommodate a wide range of packaging formats. The PRO 2 table-top units are well-suited for inspecting small to mid-sized packages, while the larger PRO stand-alone model can handle full cartons or E2 boxes. A touchscreen interface allows for intuitive operation, and optional barcode scanning streamlines user login and product selection.
The latest iteration, the LEAK-MASTER PRO 2, places a premium on usability. It features integrated LED lighting that turns blue during measurement and signals results with red for failures and green for passed tests—an interface designed for instant clarity. The unit relies on compressed air and a Venturi nozzle to generate vacuum, reducing maintenance demands and lowering operational costs. For facilities without a compressed air supply, a version equipped with an electric vacuum pump is also available.
WITT-Gasetechnik’s solution delivers an efficient, standardized approach to leak detection—one that supports quality control at scale, ensures compliance, and helps manufacturers safeguard both their products and their reputation.
