Série Levelogger Junior 3001 de Solinst


The Levelogger Junior provides an inexpensive alternative for measuring groundwater and surface water levels. It combines a datalogger, temperature sensor, pressure transducer, and 5-year battery, in a small, maintenance free, waterproof stainless steel housing.
The Levelogger Junior features a non-volatile memory, with a capacity of 32,000 sets of temperature and water level data points. Readings are linear at a user-defined interval between 0.5 second to 99 hours. Accuracy is 0.1% FS, with a lifetime factory calibration.
If greater accuracy, sampling options, or ranges are required, the Solinst Levelogger EDGE has the functionality to suit your application. For conductivity datalogging, Solinst also offers the LTC Levelogger Junior. Compatible with Levelogger EDGE software and accessories, the Levelogger Junior is also SDI-12 compatible, can communicate using a Leveloader Gold data transfer unit, and is able to integrate into Solinst Telemetry Systems.

Features
  • Low cost
  • 5 year battery life
  • 32,000 data points
  • Accuracy of 0.1% FS
  • Real Time View
  • Compatible with Levelogger EDGE Series software and accessories

Operation
Programming the Levelogger Junior 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 EDGE Software automatically detects the type of Levelogger that is connected. Programming, downloading, data management and export are easy. The Real Time View option allows immediate viewing of live water level and temperature readings. These compact dataloggers are very easy to deploy. Installation can be with direct read cables or by stainless steel wireline or Kevlar® cord suspension, avoiding the use of vented cables. The Levelogger Junior outputs temperature and compensated water level readings. The Barologger EDGE and Levelogger software allow easy barometric compensation. The Levelogger Junior also features helpful utilities such as self-test capability, a robust, non-volatile EEPROM memory and FRAM back-up memory for increased data integrity, also the ability to upgrade firmware for increased function and features.
