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 because it's:
- Pre-programmed. No user programming necessary.
- Powered by 5 AA batteries. No external power source required.
- Weatherproof. 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.
