LOCK offers a wide range of metal detectors to the food, pharmaceutical, textile, automotive and other industries. LOCK metal detectors find ferrous and non-ferrous metal particles as small as 0.15 mm diameter. LOCK sytems can be used to find ferrous metals while ignoring non-ferrous, to indicate when metal is present or when metal is absent. For over 50 years LOCK has supplied metal detectors to customers worldwide, providing reliable detection day after day in products as diverse as prescription drugs and raw meat. The Metalchek 9 is analog based and the Metalchek 30+ is the latest in digital technology - simplicity versus sophistication.

Met 30+ Digital Metal Detector
With improved detection performance, processing speeds and simplified operation, the Met 30+ is setting new metal detection standards in the packaging industry. Designed to detect real-life contaminants such as wire, the Met 30+ is equally effective in both "wet" and "dry" applications. Both rugged and robust it withstands the increasingly aggressive cleaning environments encountered throughout the food industry today.

Met 30+ Freefall Digital Metal Detector
The Freefall is designed for use with powders, granules, and free flowing solids. It can be installed at the beginning of a production line to inspect materials in bulk powder or granule form, or anywhere in the process where the product is falling freely under gravity, e.g. beneath feed hoppers and in pipelines. Freefall is also available in Met 9 Analog.

Met 30+ Digital Pharmaceutical Metal Detector
The Met 30+ is capable of detecting and rejecting microscopic contaminants in pharmaceutical production lines at speeds up to 30,000 tablets per minute. It offers the ultimate in inspection standards. The Lock "Solid" digital technology provides exceptional sensitivity even with difficult product such as high iron content ingredients or bulk presentations. It features automatic set-up and continuous automatic product tracking, all delivered with ultra high speed processing. This unit can be wheeled into or out of position for cleaning and can be adjusted for a variety of line heights and product transfer angles.
