Solinst Levelogger Junior Edge Vannstands-logger

Levelogger Junior Edge gir et billig alternativ for måling av grunn- og overflatevannstand, samt temperatur. Den kombinerer trykksensor, temperaturmåler, datalogger og 5-års batteri i en kompakt (22 mm x 142 mm) rustfri stålkasse.

  • Tilgjengelig med 5 m og 10 m trykkområde med 0,1% nøyaktighet
  • Opptil 40.000 lagrede målinger kan enkelt lastes ned ved hjelp av brukervennlig programvare
  • Automatisk kompensasjon for atmosfærisk lufttrykk når den brukes sammen med Solinst Barologger

Description

The Levelogger Junior Edge provides an inexpensive alternative for measuring groundwater and surface water levels and temperatures. The Levelogger Junior Edge combines a pressure sensor, temperature detector, data logger and 5-year battery (based on a 1-minute sampling rate) in one compact 22 mm x 142 mm (7/8" x 5,6") stainless steel housing.

The Levelogger Junior Edge records absolute pressure using the same durable Hastelloy pressure sensor as the Levelogger Edge. The Hastelloy sensor has excellent performance in harsh environments with better temperature compensation and thermal response time and can withstand 2 times overpressure without permanent damage.

The Levelogger Junior Edge features FRAM memory, with a capacity of 40.000 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 Edge has the functionality to suit your application (see Model 3001 Edge data sheet). For conductivity data logging, Solinst also offers the LTC Levelogger Junior (see Model 3001 LTC Levelogger Junior data sheet).

Applications
  • Monitoring water levels in wells and surface water
  • Pump and slug tests
  • Reservoir and stormwater runoff management
  • Watershed and drainage basin monitoring
  • Stream gauging, lake and wetland monitoring
  • Tank level measurement

Features
  • Low cost
  • 0.1% FS accuracy
  • Robust Hastelloy pressure sensor
  • Memory for up to 40.000 readings
  • Basic and advanced data compensation options

Operation

Programming the Levelogger Junior Edge is the same as with the Levelogger Edge. An Optical Reader or PC Interface Cable connects the Levelogger to a laptop or desktop PC. The intuitive Levelogger Software automatically detects the type of Levelogger 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 Junior Edge outputs temperature and temperature-compensated water level readings. Using the Data Wizard in the Levelogger Software, barometric pressure compensation from a single Barologger Edge file can be applied to multiple Levelogger Junior Edge files simultaneously.

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

These compact data loggers 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.
