ECH₂O Em50

Plug in sensors, start logging data

The Em50 is a self-contained data logger built to power, read, and log data from five sensors. All METER sensors work with the Em50; no programming is necessary.

No accessories required

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. For extended battery life try the Em50 Solar, which uses 5 AA NiMH batters and a built in solar panel.

Simple setup

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.

Stores 36,000 data scans

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.
