Collect Data via Wireless Communication with a Base Unit

Data loggers in our RTR-500 Series only function as Remote Units and need to be used with one of collection devices (Base Unit).(see complementary products tab)

The collected data can then be transmitted to a PC by a variety of methods such as USB, E-mail, or FTP. Moreover, various functions, such as the monitoring of current readings and warning notification, make it a powerful data management system. * Select a Base Unit according to the type and scale of the measuring environment.
