Model 201 Water Level Temperature Meter
The Model 201 Water Level Temperature Meter (WLT) measures static water levels, as well as temperature; ideal for profiling temperature in wells, boreholes and open water.
Accurate temperature measurements are clearly displayed on an LCD readout on the faceplate. Temperature measurements are read from -20ºC to +125ºC with an accuracy of ±0.10ºC from -5ºC to +50ºC and ±0.50ºC outside of that range. No user calibration is required.
The LCD menu is easy to operate. When profiling temperature, the buzzer is simple to deactivate as the probe is lowered to depth.
Water level and probe depth measurements are read from the Solinst durable flat tape, which is accurately laser marked each millimeter or every 1/100 ft. Tape lengths are available up to 600 m (2000 ft.).
Electronics are powered by a standard 9V battery, providing 90 hours of on-time. There is an auto-off after 8 minutes of inactivity.
Even small temperature fluctuations can have a great affect on the biological activity of aquatic organisms. Temperature also has immediate affects on the chemistry, and therefore the quality of water. As such, temperature is an important parameter to monitor.
The Model 201 Water Level Temperature Meter is ideal for:
- Profiling temperature in wells and open water
- Detecting runoff, points of inflow, or other sources of thermal pollution
- Early warning of changes in water quality, including dissolved oxygen levels and conductivity
- Monitoring and predicting changes in aquatic environments
- Geothermal studies
