Data Loggers Solinst Series Levelogger 5 Water Level

Unbeatable Precision for Water Monitoring in Any Environment

High-precision level and temperature logger, resistant to corrosion and extreme conditions, with Hastelloy® sensor, expanded memory, advanced optical communication, and telemetry options for reliable and continuous monitoring.

Levelogger 5

An excellent choice for long-term water level monitoring in a wide range of groundwater and surface water applications, including wells, lakes, streams, ports, tanks, etc. The standalone Levelogger 5 combines a Hastelloy® pressure sensor, a temperature detector, a 10-year lithium battery, and a data logger with memory for 150,000 reading sets. A single-eye optical interface allows for easy cleaning and more reliable and faster communication. The components are sealed within a 7/8˝ diameter x 6.3˝ long stainless steel housing with a corrosion-resistant baked polymer coating (inside and out). Double O-ring seals ensure excellent leak protection. The Levelogger 5 uses a Faraday cage design to protect against surges or electrical spikes caused by lightning. A Hastelloy® pressure sensor provides more stable readings under extreme pressure and temperature conditions. The Levelogger 5 measures pressure and temperature and displays temperature-compensated level readings and temperature readings. Choose from linear, event-based, or custom-scheduled sampling. The optimized software offers easy data logger programming, and simplified data compensation allows for barometric compensation of multiple data files at once. Absolute pressure (water pressure + atmospheric pressure) is measured and expressed in feet, meters, centimeters, psi, kPa, or mbar. For the most accurate water level readings, use a Barologger 5 (sold separately) to compensate for atmospheric pressure. The Levelogger 5 can be suspended on a stainless steel cable or Kevlar® cord. You can also use an optional L5 direct read cable (sold separately) to connect the Levelogger 5 to the surface for easy data download and reprogramming without removing the unit from the water. Programming the Levelogger 5 is easy. Simply connect it to a PC using an optical reader (Desktop Reader 5 or Field Reader 5, each sold separately) or a PC interface cable. A single screen allows you to complete project information and sampling regime. Configuration templates can be saved for convenient use.

Levelogger 5 LTC

Records water level, temperature, and conductivity. The single-eye optical interface is easy to clean and scratch-resistant. Combines a data logger, an 8-year battery, a Hastelloy® pressure sensor, a temperature detector, and a conductivity sensor in a waterproof 7/8˝ x 8.2˝ housing. A baked polymer coating protects the body against corrosion, abrasion, and high temperatures.

Levelogger 5 Junior

An economical alternative for measuring groundwater and surface water levels, as well as temperature. The single-eye optical interface ensures fast and reliable communication. Combines a data logger, a temperature detector, a Hastelloy® pressure sensor, and a 5-year battery in a 7/8˝ x 6.3˝ stainless steel housing.
