Solinst 201 WLT Temperature and Water Depth Gauges

Solinst Model 201: Water Level and Temperature in a Single Measurement

A robust meter that combines accurate level reading and temperature profiling in wells, tanks, and open water, featuring a clear display and high-durability tape.

The Model 201 Water Level and Temperature Meter is ideal for static water level measurements, as well as water temperature profiling in wells, tanks, and open water. Precise temperature measurements are clearly displayed on an LCD screen on the faceplate of the reel, from -20ºC to +125ºC.

Water level and probe (tip) depth are measured directly on the high-durability flat tape with laser markings. Tape lengths are available up to 2000 feet (600 meters).

Also from Solinst, the Model 107 TLC Meter measures water level, temperature, and conductivity (see Model 107 TLC Meter datasheet). For continuous monitoring and logging of water level and temperature data, see the Model 3001 Levelogger Edge datasheet.

Water Level and Temperature Meter Probe: The 201 probe is made of high-quality 316 stainless steel. The pressure-proof probe can be submerged along the full length of the tape. The probe's zero measurement point is near the tip, keeping water displacement to a minimum. A probe shroud protects the sensor tip.

The temperature sensor is located at the tip of the stainless steel probe; however, since the probe body acts as a heat conductor, best resolution is obtained when the probe is fully submerged. The tape seal and probe design allow the probe to be easily disconnected for replacement if necessary.

Water Level and Temperature Meter Applications: Water temperature has a direct effect on biological activity in aquatic plants and animals, as well as many aspects of water quality and chemistry; therefore, it is a key parameter to monitor. The Model 201 Water Level and Temperature Meter is ideal for:

• Temperature profiling in wells and open water.
• Detecting leaks or inflows of run-off 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 investigations.
