Lock was founded in 1949 and has grown to become the world's leading independent supplier of industrial metal detection equipment.
The food processing and pharmaceutical industry sectors in the UK became uniquely dominated by a small group of retailers and manufacturers who demanded stringent safety and quality in their products. This environment enabled Lock to develop world-beating sensitivity and performance from their machines, and as a result they became a major supplier of detection equipment to the world's food and pharmaceutical and textile manufacturing corporations.
In 1999, a sales and service support office was established in the Netherlands to provide enhanced support to long-established users of Lock systems across the Benelux countries. Lock's continued growth and expansion into Europe was further enhaned in 2000 with the acquisition of its French Distributor Qualimatic - recently renamed Lock Inspection Systemes S.A.R.L
Lock metal detectors are installed all around the world and the company has a sales and customer service network established in over 50 countries.
