Non-Linear Junction Detector

PKI 4170Print

With this device, we break another record. Size and weight allow to take it in the pocket. Despite these minimum dimensions, the PKI 4170 also offers the full comfort of the NLJD series. Automatic frequency hopping and adjustment to the transmission power. Its handy design is ideal to check persons for hidden electronics. The transmission power emitted in the process (electro¬magnetic effect) is lower than that of a mobile phone. The high detection potential resulting from the high resonator frequency of 2400 – 2483 MHz as well as the compact antenna with a thickness of 18 mm are cutting edge in the field of NLJDs.
