EM50 Data Logger

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 Em50 is a self-contained data logger built to power, read, and log data from five sensors. All Decagon sensors work with the Em50; no programming is necessary.
  • The Em50 doesn’t need an enclosure or an external power source. The logger case itself is rated NEMA 4, IP55 for long-term outdoor use, and the logger will run (and power its sensors) for one to three years, depending on your measurement interval, on 5 AA batteries.
  • The Em50 has 5 sensor ports and one com port. Rather than having a screen and a keyboard, the Em50 is configured by plugging a laptop or handheld into the 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. The Em50 can store more than 36,000 data scans.
  • The Em50G Telemetry Data Logger allows logged data to be transmitted from the logger to Decagon’s server via internal cellular/mobile communication.
