OTT ecoLog 800 Water Level Logger
Groundwater level and conductivity sensor with built-in datalogger and telemetry
The OTT ecoLog 800 is a self-contained system for measurement of water level, temperature, and conductivity in groundwater and surface water applications. The ecoLog 800 features a complete in-well solution for groundwater measurement and flexible remote data transmission options.
- Surface water, Groundwater
- Vented pressure cell and 4-electrode graphite conductivity cell
- Waterlevel/Pressure, Water temperature, Conductivity
- Measures, stores, and transmits water level and temperature data
- 0 … 4, 10, 20, 40, and 100 m
- ± 0.05% FS
- Yes
- Remote data transmission: receive data, status messages, and low power warnings from the office via SMS, FTP, HTTP, and e-mail, eliminating field visits for data download and troubleshooting
- Complete in-well solution: all components are inserted into the groundwater well, eliminating the possibility of instrument vandalism
- Battery life: up to 10 years with lithium batteries, all batteries are field-replaceable without additional tools
- Long-term accuracy: a robust ceramic pressure cell will not deform over time, and an accurate 4-electrode conductivity measuring cell provides outputs for salinity and total dissolved solids (TDS)
- User-friendly interaction: only one program required to setup unit and download data, plus a simple infrared communication interface that provides easy on-site data download
Continuous or real-time water level, temperature, and conductivity measurement of:
- Groundwater wells
- Streams, rivers, channels, and canals
- Reservoirs, lakes, and wetlands
Ideal for monitoring:
- Continuous water level / water quality networks
- Short-term or long-term projects
- Salt water intrusion
- Aquifer storage and recovery

I want to measure, besides level and temperature, also conductivity with the ecoLog 1000, how do I do this
Not possible in current version, ecoLog 800 is still available.
