Read full description

Narda introduces an innovative way to display EMF measurements information by LR01 in combination with a dedicated APP. LR-01 is an ideal solution for EMC applications, in chambers and TEM/GTEM cells, and in EMF applications. LR-01 is a programmable logger repeater directly connected to a personal computer via optical fiber cable to USB adapter. It is also possible to connect to PCs, smartphones and tablets via USB, Wi-Fi and Bluetooth. With its internal rechargeable battery and dedicated SW, it measures electric and magnetic fields through more than 32 different probes and immediately records and plots the results. The probes can be attached to the dedicated heavy-duty connector on the LR-01 via the specific adapter,which also features excellent shielding properties and can therefore be used at very high EMF field strengths without interference. In addition to the standard Narda Probes Manager software delivered with the Logger Repeater, the communication and control protocol is freely available so users can fully control the LR-01 with their usual test software. LR-01 provides also programmable on-board acoustic, visual and vibration alarms.
