The Levelogger 5 Junior provides an inexpensive alternative for measuring groundwater and surface water levels and temperature.

The Levelogger 5 Junior combines a pressure sensor, temperature detector, a data logger, and 5-year battery (based on a 1-minute sampling rate) in one compact 22 mm x 160 mm (7/8" x 6.3") stainless steel housing.

The Levelogger 5 Junior records absolute pressure using the same durable Hastelloy® pressure sensor as the Levelogger 5. The Hastelloy sensor has an excellent performance in harsh environments and can withstand 2 times overpressure without permanent damage.

The Levelogger 5 Junior features a memory with a capacity of 75,000 sets of temperature and water level data points. Readings are linear at a user-defined interval between 0.5 seconds to 99 hours. Accuracy is 0.1% FS with lifetime factory calibration.

If greater accuracy, more sampling options, or wider depth ranges are required, the Solinst Levelogger 5 has the functionality to suit your application.

Features

  • Robust Hastelloy pressure sensor
  • Single-eye optical for fast, reliable communication


Operation

Programming the Levelogger 5 Junior is the same as with the Levelogger 5. A Desktop Reader 5, Field Reader 5 or PC Interface Cable connects the Levelogger to a laptop or desktop PC. Levelogger Software automatically detects the type of data logger that is connected. Programming, downloading, data management, and export are intuitive tasks. The Real Time View option allows immediate viewing of live water level and temperature readings, independent of the scheduled programming intervals.

The Levelogger 5 Junior outputs temperature and temperature compensated water level readings. Using the Data Wizard in the Solinst Levelogger Software, you can barometrically compensate multiple Levelogger 5 Junior files simultaneously, with just one Barologger 5 file.

The Levelogger 5 Junior is compatible with Levelogger 5 Series accessories, including the Solinst Levelogger 5 App Interface, DataGrabber 5 data transfer device, SDI-12 Interface Cable, and Solinst Telemetry Systems.

These compact dataloggers are straightforward to deploy. Installation can be with direct read cables, by stainless steel wireline or Kevlar® cord suspension, with the option of using Solinst 2" Locking Well Caps.
