The Levelogger 5 records highly accurate groundwater and surface water level and temperature measurements.

It combines a pressure sensor, temperature detector, 10-year lithium battery, and datalogger, sealed within a 22 mm x 160 mm (7/8" x 6.3") stainless steel housing with a corrosion-resistant coating baked-on using polymerization technology.

The Levelogger 5 measures absolute pressure using a Hastelloy® pressure sensor, offering high resolution and an accuracy of 0.05% FS. Readings are stable in extreme pressure and temperature conditions. The Hastelloy sensor can withstand 2 times over-pressure without permanent damage. Combined with the durable coating inside and out, the Levelogger 5 has high corrosion and abrasion resistance in harsh environments.

The Levelogger 5 uses a Faraday cage design, which protects against power surges or electrical spikes caused by lightning. Its durable maintenance-free design, high accuracy, and stability make the Levelogger 5 the most reliable instrument for long-term, continuous water level recording.

Upgraded Features

  • Increased stability for communication: single-eye optical interface—easier to clean, more scratch-resistant
  • Increased memory: 150,000 sets of data
  • Stronger, more robust design: double o-ring seals for increased leakage protection
  • Better thermistor sensitivity: upgraded platinum RTD
  • Superior protection in harsh environments: corrosion and abrasion resistant coating—inside and out
  • Enhanced Levelogger Software: improved Diagnostic Utility for more proactive user “self-tests”

The Levelogger 5 features a smooth, single-eye optical interface, which allows for easy cleaning and more reliable, faster communication. Using a Solinst USB device, including the new Field Reader 5, and Levelogger PC Software, programming, and data downloading speeds are 57,600 bps.

Flexibility for communications

Levelogger Software is streamlined, making it easy to program dataloggers, and view and compensate data in the office or the field. Data compensation is made simple; multiple data files can be barometrically compensated at once.

The Levelogger 5 App Interface on your in-field Leveloggers creates a Bluetooth® connection between your dataloggers and the Solinst Levelogger App on your smart device. Also an option, the DataGrabber 5 is a field-ready USB data transfer unit.

Remote monitoring options include the LevelSender 5, a simple and compact device that fits right in a 2" well, STS 5 Telemetry Systems, and the RRL 5 Remote Radio Link. In addition, Levelogger 5 Series data loggers are SDI-12 compatible.
