Decagon Em50G Wireless Cellular Data Logger

Download Data Even From Remote Locations

You always want to know what's going on at your research site.  But figuring out how to communicate with your data logger has typically been complicated and expensive.  The Em50G lets you check in on your data logger from virtually anywhere in the world.  The Em50G is a self-contained data logger built to power, read, and log data from five sensors. Logged data are transmitted from the logger to Decagon's server via internal cellular/mobile communication. All Decagon sensors work with the Em50G; no programming is necessary.

How it works

The Em50G uses an internal cell modem to automatically send data to an internet server four times a day. The stored data are available for you to access, monitor and download at any time.

Plug in Sensors, Start Logging Data

The Em50G powers, reads, and logs data from five sensors. All Decagon sensors work with the Em50G; no programming is necessary.

Ready to Go

The Em50G takes about 20 minutes to set up. It comes complete with a data plan and is self-enclosed and self-powered. The logger case is rated NEMA 4X, IP45 for long-term outdoor use, and the logger will run (and power its sensors and the cell modem) for about six months on 5 AA batteries.

Simple Setup

The Em50G has 5 sensor ports and one communication (download) port. Rather than having a screen and a keyboard, the Em50G is configured by plugging a laptop or handheld into the com port. ECH2O Utility software (included) provides setup windows where you set the logger clock, select the type of sensor on each port and specify how often you want the sensors read.

Easy Connectivity Check

See signal strength and connection quality in real time as you pick the best spot for the data logger. This feature lets you test connectivity at your measurement site BEFORE you install the logger.

Data Safeguards

Transmitted data is backed up in the data logger memory to give you an extra layer of data protection. A "confirm data transfer" protocol makes sure data transmission is correct and complete.

Stores 36,000 Data Scans

The Em50G stores over 36,000 data scans. A scan includes the date, time and measurements from each of the five ports.
