WITT Gas has expanded its LEAK-MASTER PRO and PRO 2 series for non-destructive leak detection in modified atmosphere packaging, covering formats used across food, pharmaceutical, and consumer goods production.
The systems use CO2 sensor technology to identify escaping gas from packages under vacuum. Because CO2 is already used in many modified atmosphere packs, the method avoids the need for helium as a tracer gas and allows products to remain intact after testing.
WITT says the LEAK-MASTER PRO and PRO 2 series can detect microleaks as small as 10 micrometers, depending on the product and test conditions. In MAP production, small seal defects can shorten shelf life, damage product quality, and increase recall exposure, particularly where high-speed packaging lines are running multiple formats.
The LEAK-MASTER PRO 2 is designed for smaller individual packages and small to medium-sized formats. It uses a chamber evacuated by a compressed-air Venturi nozzle, with an electric vacuum pump available as an option. The system includes LED status indication, touchscreen operation, optional barcode reader support, Ethernet-based data transfer, and a low-maintenance design for production quality control environments.
The larger LEAK-MASTER PRO is intended for bigger formats, including cartons and E2 boxes. It combines CO2-based leak detection with stainless steel housing, touchscreen controls, an electric vacuum pump, and data transfer options via Ethernet or WLAN.
Across both models, the test cycle is automated and operator-independent. Users place the package in the chamber, select the relevant programme, and run a defined vacuum and test cycle. If CO2 escapes from the pack, the sensor detects the change in the chamber atmosphere and records the result.
The repeatable process supports quality assurance across multiple product lines, pack sizes, and shifts. Product selection and user login can also be handled through an optional barcode reader, reducing the risk of manual input errors when switching between formats.
The systems support a move towards more measurable seal integrity control in packaged goods production. Faster lines and more varied pack formats make periodic destructive testing a limited safeguard against process drift. Non-destructive leak testing allows manufacturers to increase inspection frequency while preserving tested products for sale or further analysis.
