Description

The LTC Levelogger Junior logs conductivity, as well as water level and temperature. Like the LT Levelogger Junior Edge, it is easy to transport, program, deploy and retrieve data. It combines a data logger, 5-year battery, Hastelloy pressure sensor, temperature detector, and conductivity sensor within a small 22 mm x 190 mm (7/8" x 7.5") waterproof housing.

The conductivity sensor is a 4-electrode platinum sensor with auto-ranging capabilities. The minimal maintenance, sealed LTC Levelogger Junior is simple to clean and calibrate, even in the field.

Using Levelogger Series Software, it displays conductivity, temperature, and temperature-compensated water level. Memory is non-volatile and stores up to 16.000 sets of readings. Measurements are linear, in any interval between 5 seconds and 99 hours.

Applications
  • Salt water intrusion and soil salination monitoring
  • Plume remediation monitoring and studies
  • Leachate monitoring at landfills, mine tailings, waste disposal storage sites, and more
  • Agricultural and stormwater runoff monitoring
  • Tracer tests

Features
  • Low cost
  • 0.05% FS accuracy
  • Corrosion resistant Hastelloy pressure sensor
  • Three measurements in one probe
  • Single- or multi-point calibration
  • Basic and advanced data compensation options

User-Friendly Operation

Calibration and Data Wizards guide you through the calibration process and barometric compensation to provide corrected data. Levelogger Software allows you to easily program your preferences, download data, display data in a graph or table format or export to other programs. The LTC Levelogger Junior can also be used with the Solinst Levelogger App.

The Real Time View option allows immediate viewing of live conductivity, water level and temperature readings. Leveloggers are easy to deploy; installation can be with direct read cables or wireline/cord suspension, avoiding the use of vented cables.

The LTC Levelogger Junior is SDI-12 compatible, can communicate with a DataGrabber data transfer device, and is able to integrate into a Solinst Telemetry System (see Model 9100/9200 data sheet).
