Anritsu CW and MD systems combine checkweighing and metal detection in 1 package; they provide the 2 functions simultaneously. The integrated checkweigher handles hundreds of products per minute with a potential accuracy of +/-.01g, depending on the application. Adopting a 2-frequency magnetization detection method, the systems detect ferrous and stainless metals at the same time, independent of each other.
