The ELEKTRON-MD series of detectors has a non-contact auto-learning system, unprecedented in other detectors. The non-contact auto-learning system analyzes the tested product and automatically saves the detection parameters (e.g. the influence of the product itself and the background of the environment). The detector, controlling the transporter, automatically moves the product through the detection probe window back and forth until the learning is completed. This solution facilitates work, especially with heavy products. Thanks to this, learning is much more accurate without interference and also increases the level of detection and stability of the metal detector.
