EM50 Data Logger

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 of our 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 on 5 AA batteries.

Simple Setup

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 where you 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 stores more than 36,000 data scans. A scan includes the logger name, date, time and measurements from each of the five ports.
