Em50 data logger
a low-cost, basic data logger
- A low cost, plug and play data logger for Decagon / METER Environmental sensors
- Large internal storage of 36,000 scans
- Power supply from 5 x AA batteries for at least 6 months
- USB download for rapid data collection
- Environmental proof enclosure
- Simple, pre-programmed and ready to go
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 communication port. Rather than having a screen and a keyboard, the Em50 is configured by plugging a laptop into the comm port. The included ECH2O Utility software 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. A scan includes the logger name, date, time, and measurements from each of the five ports.
