Solnist Model 201 Water Level Temperature (WLT) 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 PVDF flat tape. Tape lengths are available up to 600 m (2000 ft).

Water Level & Temperature Probe

The 201 Water Level Temperature Meter Probe is made of high quality 316 stainless steel. The pressure-proof probe can be submerged to 1000 ft (300 m). The zero measurement point on the probe is close to the tip, keeping water displacement at a minimum.

The temperature sensor is located at the stainless steel tip of the probe, however, since the probe body acts as a heat sink, best accuracy is obtained when the probe is completely submerged. The tape seal plug design allows the probe to be easily replaced, if required.

Water Level & Temperature Applications

Water temperature has a direct affect on the biological activity of aquatic plants and animals, as well as many aspects of water quality and chemistry; therefore, it 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 drilling and studies
