Em50 Datalogger:
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.

Features:

Very low power consumption.
Uses five AA alkaline batteries.
UV-resistant NEMA 4X/IP45 enclosure.
1 MB of memory (33,000 data points).

Em50R Datalogger:
The Em50R has a radio telemetry module that can transfer data to a DataStation or Rm1. The radio module uses 900 MHz or 2.4 GHz spread spectrum RF communication (depending on government regulations). Broadcast range depends on radio type and terrain/interference, but all loggers have an external RSMA connector for use with antennas.
