Lock says its MET 30+ hf metal detector offers up to 30% higher sensitivity than standard metal detectors.  The unit employs a high-frequency, crystal controlled oscillator and is designed for a variety of food products for which sensitivity to stainless steel is a primary concern.  The unit inspects dry foods such as biscuits or chips at 875Khz. The detectors include ADC software and a touch-screen interface.
