The Em50 is a 5-channel, self-contained data recorder designed for use with any ECH2O sensor. The sensors are plugged into the 5 channels and measured as directed by the user. Housed in a weatherproof enclosure with an O-ring seal, the Em50 is ideal for long-term outdoor use. With minimal battery usage, the Em50 can take readings as often as once per minute for over a year. Any combination of the listed sensors can be used. The Em50 can be used with ECHO Utility software which allows you to configure and program your loggers, download data, scan the ports and save data directly in MS Excel format. The Em50 is compatible with any ECH2O sensor.
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.
EM50 series of Data Loggers Features
You always want to know what’s going on at your research site. But figuring out how to communicate with your data logger is typically 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.
The standard Em50G uses an internal cell modem to automatically send data to an internet server four to six times a day (contact Decagon for more frequent data delivery options). The stored data are available for you to access, monitor, and download at any time.
Decagon has over 120 cellular/mobile GSM partners all over the world. To check and see if your site is covered, contact Decagon or your local representative with your site’s lattitude and longitude. If you’re still not sure, you can demo an Em50G from Decagon and take it to your site to double check.
The Em50G powers, reads, and logs data from five sensors. All Decagon sensors work with the Em50G; no programming is necessary.
The Em50G generally takes about 20 minutes to set up. It comes complete with a data plan, and is both 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.
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 its com port. ECH2O Utility software (included) provides setup windows which name the logger, set the logger clock, select the type of sensor on each port, and specify how often you want the sensors read.
See signal strength and connection quality in real time as you pick the best spot for your data logger. This feature lets you test connectivity at your measurement site BEFORE you install the logger.
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.
The Em50G stores over 36,000 data scans. A scan includes the date, time, and measurements from each of the five ports.
