JJN Digital EDD-24T Non-Linear Junction Detector

The JJN Digital EDD-24T is handheld Non-Linear Junction Detector (NLJD) designed to be compact and portable. The EDD-24T NLJD is able to detect semiconductor circuits in electronic devices, such as listening devices, cameras or tracking devices. Whether the device is transmitting, turned on or is connected to power is irrespective to the JJN Digital EDD-24T NLJD, it’s still able to detect the device.

The presence of electronics is detected through second and third harmonic detection and in the event of a false detection, the EDD-24T NLJD suggests silicon, electronics or metal with an added algorithm.

The bright and intuitive display enables the operator to view the EDD-24T’s built-in screen even in bright conditions. Combined with the EDD-24T’s ergonomically placed controls that allow for one handed control, the EDD-24T NLJD is user friendly and easy to operate.
