ETM has successfully deployed numerous ETM Green units to provide temperature
alarm functionality in remote areas where fixed-coms and power connections are not
available.
Featuring an internal lithium battery pack, ETM Green units can operate
for extended periods without power. Alarms can be sent by SMS and/or IP and
logged data is available online using ETM’s ekoCALM service.
ETM Green units can also be used for rainfall alarms, level monitoring,
pulse counting, and gate alarms.
