Now Available with Optional Triple Frequency Controls

New integrated controls enhance the company’s innovative imagePHASE platform by allowing the processor to learn a packaged food product in three different conditions, and select the one with that yields the greatest sensitivity. With the upgrade to these controls, the detector also displays the expected sensitivities to the operator with all three metal types – ferrous, non-ferrous and stainless steel.
