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.
