Solinst Model 201 Water Level Temperature Meter
The Model 201 Water Level Temperature (WLT) Meter is ideal for measuring static water levels, as well as profiling temperature in wells, boreholes, tanks and open water.
Accurate temperature measurements are clearly displayed on an LCD readout on the faceplate, from -20ºC to +125ºC. Water level and probe depth measurements are read off the Solinst durable laser marked flat tape. Tape lengths are available up to 600 m (2000 ft).
Features:
Accurately measure temperature from -20ºC to +125ºC
Tape lengths to 600 m (2000 ft)
Durable, corrosion and chemical-resistant flat tape
Standard 9V alkaline battery gives 90 hours of use
Automatic shut-off after 8 minutes
Sturdy, standalone reel with ergonomic handle and brake
No user calibration is required
Applications:
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
