Understanding Challenging Applications For Improved Metal Detection

In the food and pharmaceutical industries many of the products being inspected for contamination exhibit a phenomenon known as ‘Product Effect’. This is where the type of product being inspected, can itself hinder the inspection technologies capability to identify that particular contaminant.

Other inspection technologies may refer to this phenomenon differently but for metal detection technology the extent of this effect normally categorises products as being either "wet" or "dry". The purpose of this white paper is to explain what is meant by these terms and also to develop an understanding as to why this is important when choosing the right metal detector to use.
