OTT – ecoLog 800 Water Level Logger

Description

OTT – ecoLog 800 Water Level Logger

Groundwater level and conductivity sensor with built-in datalogger and telemetry

• Application: Surface water, Groundwater
• Measurement technology: Vented pressure cell and 4-electrode graphite conductivity cell
• Parameters measured: Waterlevel/Pressure, Water temperature, Conductivity
• Product Highlights: Measures, stores, and transmits water level and temperature data
• Measurement range: 0 … 4, 10, 20, 40, and 100 m
• Accuracy: ± 0.05% FS
• Internal data logger: Yes
  

Advantages:

• 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

Example of Use:

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
