Water level measurement accuracy Solinst is known for, with the addition of convenient temperature profiling.
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 2000 ft (600 m).
Also from Solinst, the Model 107 TLC Meter measures water level, temperature and conductivity. (See Model 107 TLC Meter Data Sheet). For datalogging of water level and temperature, see the Model 3001 Levelogger Edge Data Sheet.

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 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
When the meter is turned on, the LCD screen displays the firmware version of the WLT Meter (e.g. "WLTM 1.0") for about two seconds. The LCD will then display the temperature reading, in or out of water.
The LCD menu is simple to operate. Pressing the button two times quickly deactivates the buzzer (the light stays active). To reactivate, press the button two times quickly. To turn the meter off, press and hold the button for two seconds.
