Metal detectors are many times assembled at the end of the production line and are therefore the last critical control point (CCP). It is very important to monitor the sensitivity of the detector on a regular basis. Magnetech is a supplier of test pieces for your metal detector. The test wands are made from food safe plastic and come in a variety of colours. Each test piece comes with a certificate of conformity which shows the composition of the piece. Test wands are normally used on conveyor metal detector applications.
