The NZR-7B is connected to the cable between the data logger and the switching box. If a surge current is induced in the cable by lightning, the NZR-7B works to route the surge current to ground so that the data logger and the switching box are not damaged. Furthermore, relays are equipped in the NZR-7B to electrically disconnect the connection between the data logger and switching box when they are not measuring. This function increases ability in protecting instruments from surge current.


Automatically disconnect between the instruments to block a surge current
Either soldering or NDIS plug is possible for cable connection
