Leaking modified atmosphere packaging (MAP) poses a significant risk for food manufacturers. It can shorten product shelf life, lead to spoilage, and cause costly product recalls. To meet these challenges, WITT offers the LEAK-MASTER® PRO/PRO 2 series. These leak detectors reliably identify even microleaks as small as 10 micrometers. They operate quickly and completely non-destructively. The result for food manufacturers: maximum product quality and food safety with minimal effort — for satisfied customers and consumers.
CO₂ Sensor Technology: Fast and Accurate Results — Operator-Independent and Standardized
The high precision of the LEAK-MASTER® PRO/PRO 2 series is based on advanced CO₂ sensor technology. Since CO₂ is already included in most shielding gas packaging, it offers a much more cost-effective alternative to test gases like helium. The testing process is extremely simple and highly effective: A vacuum of up to 200 mbar absolute is generated in the measuring chamber. The resulting pressure difference causes CO₂-containing inert gas to escape from any leaking packaging. Highly sensitive sensors detect this gas within seconds, enabling the detection of even the smallest leaks.
The rapid inspection process saves valuable time and resources. The entire procedure is fully automated, ensuring operator-independent and standardized results. This guarantees maximum reliability and reproducibility, while also simplifying certification. Because the test is non-destructive, products can be sold immediately afterward, and there is no waste.
Suitable Testing Devices for All Packaging Sizes
The LEAK-MASTER® PRO/PRO 2 series is designed for maximum practical flexibility. Five different chamber sizes are available to accommodate a variety of packaging dimensions. The PRO 2 tabletop devices are ideal for precise, individual inspection of small to medium-sized packages. For larger packaging, including complete cartons or E2 boxes, the large PRO stand-alone device is the preferred choice. All devices are operated quickly and easily using a touch display. To further streamline operations, user login and product selection can optionally be performed via barcode reader.
Highlights of the PRO 2: Integrated LED Lighting and Compressed Air Operation
The latest-generation LEAK-MASTER® PRO 2 is designed for simple operation and maximum user convenience. One standout feature is its integrated LED lighting: it glows blue during testing and signals the result in red (“failed”) or green (“passed”). This makes the process extremely intuitive for users.
The vacuum in the PRO 2 is generated using compressed air and a Venturi nozzle as standard. This design makes the device highly durable and low-maintenance, significantly reducing operating costs. An optional version with an electric vacuum pump is also available for facilities without access to compressed air.
Digital Documentation for Seamless Quality Assurance
All test processes are digitally recorded in the device memory. Measurement results — including date, time, product information, and tester name — can be archived using WITT software. Exporting data as a CSV file, for use in applications like Microsoft Excel®, is also supported.
