    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 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 METER’s server via internal cellular/mobile communication.  All METER sensors work with the Em50G with the exception of ATMOS 41, and no programming is necessary.

    How it works

    The standard Em50G uses an internal cell modem to automatically send data to an internet server four to six times a day (contact METER for more frequent data delivery options). The stored data are available for you to access, monitor, and download at any time.

    Is my site in a coverage area?

    METER has over 120 cellular/mobile GSM partners all over the world.  To check and see if your site is covered, contact METER or your local representative with your site’s latitude and longitude.  If you’re still not sure, you can demo an Em50G from METER and take it to your site to double check.

    Plug in sensors, start logging data

    The Em50G powers, reads, and logs data from five sensors.All METER sensors work with the Em50G, with the exception of ATMOS 41, and no programming is necessary.

    Ready to go

    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. For extended battery life try the Em50G Solar, which uses 5 AA NiMH batteries and a built in solar panel.

    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 into its comm 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.

    Easy connectivity check

    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.

    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.

  • Picture

  • Description

    Plug in sensors, start logging data

    Like our standard Em50 and Em50G, these self-contained data loggers are built to power, read, and log data from five sensors. Our solar loggers use rechargeable nickel-metal hydride (NiMH) batteries and a built in solar panel for extended deployments. Pull the battery tab to power on the logger and the NiMH batteries will charge automatically. The logger case is rated NEMA 4, IP55 for long-term outdoor use. All METER sensors work with Em50/Em50G Solar Data Loggers, with the exception of ATMOS 41, and no programming is necessary.

    Simple configuration

    Like their counterparts, the Em50 Solar and Em50G Solar have 5 sensor ports and one communication port. They are configured by plugging a laptop into the comm port. The included ECH2O Utility software provides setup windows to name the logger, set the logger clock, select the type of sensor on each port, and specify how often you want the sensors to read.

    Remote data access

    The Em50G Solar lets you check in on your data logger from virtually anywhere in the world. Data are transmitted from the logger’s internal GSM cellular module to METER’s secure server via cellular communication. The password-protected data are available for you to access, monitor, and download at any time. Transmitted data is backed up in the data logger’s memory to give you an extra layer of data protection. A “confirm data transfer” protocol makes sure data transmission is correct and complete.

  • Picture

  • Description

    Low cost analog mini-logger

    The Em5b is a low cost, limited use five-channel mini-logger. It powers and reads the EC-5, GS1, and 10HS soil moisture sensors, the ECRN-50 and ECRN-100 rain gauges, and the ECT temperature sensor.

    Designed for use over the growing season, the Em5b runs for 5-6 months on 4 AAA-size alkaline batteries and has 46 kB of flash data memory (138 days at 1 scan/hour).

    The Em5b comes with ECH2O Utility software for setting up and downloading data.

    Advantages

    • Cost. The Em5b allows you to add inexpensive peripheral sites to a study.
    • Perfect for a season’s worth of basic soil moisture data.

    Limitations

    • Limited weatherproofing. Needs to be protected from the elements.
    • Not optimized for frequent data downloads. Port 1 must be unplugged before dowloading data; case closures can be cumbersome.
    • Only reads analog sensors (listed above).
