OTT ecoLog 1000 Water Level Logger

Self-contained groundwater level logger for measuring water level and temperature with integrated mobile communication

The OTT ecoLog 1000 is a self-contained, cellular groundwater level logger for measuring water level  and  temperature. It  provides  reliable  system  up-time  and  accurate  measurements  while   avoiding data gaps. It’s simple to operate using just a smart phone or PC via integrated Bluetooth Low  Energy  (BLE)  -  no  additional  tools  for  maintenance  or  battery  replacement.  It  supports  mobile devices, smart phones, and tablets operating with Android, iOS or Windows 10. Configure  and  monitor  your  data  remotely  with  integrated  two-way  mobile communication  to avoid  unnecessary,  expensive  trips  to  your  measurement  site  and  send  encrypted  data  with automatic retries if transmission fails.

The ecoLog 1000 with 4G/2G module will replace the ecoLog 500.
