Enabling better global research outcomes in soil, plant & environmental monitoring.

EM5B Data Logger

The Em5b is a low cost, limited use five-channel mini-logger. It powers and reads the EC-5, GS1, 10HS, EC-10, EC-20, ECT and RT-1 temperature, as well as the ECRN-50 and ECRN-100 rain gauges.
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 designed to be accessed on a weekly basis. Port 1 must be unplugged before downloading data; case closures can be cumbersome.
  • Only reads analogue sensors (listed above).
