Continuous Data Loggers
- Applications:
Looking for a logger to power your sensors and read and store the measurement data? The Em50 series simplifies data logging with:
- Pre-programming. No user programming necessary.
- An internal power supply (5 AA batteries). No external power source required.
- Weatherproofing. No extra enclosure needed.
Just plug in any sensor Decagon sells, set your sensor type and measurement intervals using drop-down menus, and start logging data.

Accessories
DataStation
Collects data wirelessly from up to 80 data loggers within radio range (typically 1-3 miles). Stores 36,000 packets of data.
Rm-1
The Rm-1 is a radio modem used for real-time connection to the Em50R data loggers. The RM-1 can also be used as a repeater in the wireless system. Use the Rm-1 with to change the logger name, logger date/time, sampling interval, and ports sensors assignments. You can also use it to download logged data all remotely from the convenience of your computer.
