THS / 3F metal detectors and their narrower version THS / SL-3F are designed for applications with limited space.

These models work at three different frequencies to eliminate the effect of material effects on the metal detection process. So these metal detectors work well on lines where products that are very different from each other may appear. The frequency selection process itself is carried out automatically. Multi-frequency metal detectors offer a high level of sensitivity, independent of the travel speed of the product being tested, and high resistance to interference occurring in an industrial environment, thus meeting the strict requirements of quality control systems according to ISO 9001. Metal detectors allow the detection of magnetic and non-magnetic metals, and stainless steel , they can also automatically adapt to the properties of the tested products. The THS / 3F and THS / SL-3F metal detectors allow statistics of controlled products (separately for each type), counting all controlled and contaminated products separately.
