That gas is already contained in most inert gas packaging and is also much cheaper than helium, for example. The acrylic glass test chamber is evacuated. In the event of a leak, the pressure difference between the test product and the chamber causes gas to be extracted from the packaging. Highly sensitive gas sensors detect this gas within a few seconds. The product is not damaged and can be sold. This procedure is proven and effective.
The PRO 2 is equipped with a number of innovations that significantly increase the performance for the user: For example; with optimized chamber size and compressed air instead of a vacuum pump to generate the vacuum. As a result, the device also finds micro-leaks down to 10 micrometres (depending on the product and the test conditions) with high precision and, above all, even faster.
The quality inspector therefore needs less time per test. In practice, 8 seconds testing time is already sufficient for many types of packaging. The compact design also scores points with its low space requirement. Another advantage: The Venturi nozzle used for vacuum generation is extremely low-maintenance and durable, which significantly reduces operating costs. If no compressed air connection is available, an optional version with an electric vacuum pump is also available.
Witt’s developments also enable the simplest possible operation. The easy opening lid with springs allows simple, energy-saving filling. Operation is via touch screen with graphic interface. As an option, product selection and user login can also be carried out using a barcode reader, which further accelerates the processes.
An optical highlight of the new PRO generation: a surrounding LED illumination provides a clearly visible signal. During measurement, the device lights up blue, after completion of the test it either lights up red or green depending on the result. It couldn't be more intuitive or simple for the user.
The LEAK-MASTER PRO 2 manages up to 1,200 products as well as names, passwords, and barcodes of 60 users. Measurement data documentation is carried out with the aid of special Witt software. All measurement results including date, time, product details and name of the inspector can thus be digitally archived and additionally analyzed, for example using MS-Excel. The LEAK-MASTER PRO can be integrated into your company network via the Ethernet interface.
