Solinst Levelogger 5 LTC Vannstands- & Konduktivitetslogger

Solinst Levelogger 5 LTC er en kostnadseffektiv logger for måling av konduktivitet, nivå og temperatur i overflate- og grunnvann. Den har et 4-elektroder platina-element for overlegen ytelse i konduktivitetsmålinger.

  • Lett å rengjøre og kalibrere, selv i felt
  • Opptil 100.000 lagrede målinger kan enkelt lastes ned med intuitive programvare
  • 8-års batterilevetid basert på 5-minutters sampling intervall


The LTC Levelogger Edge logs conductivity, 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, 8-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 Edge 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 27.000 sets of readings.

  • 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

  • Corrosion resistant Hastelloy pressure sensor
  • Titanium ceramic PVD coating
  • 4-electrode platinum conductivity 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 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. The LTC Levelogger Edge is SDI-12 compatible using the Solinst SDI-12 Interface Cable.

Data can be downloaded in the field using the DataGrabber™ USB data transfer device, or through Bluetooth® using the Levelogger App Interface device. The LTC Levelogger Edge is also compatible with the 9500 LevelSender telemetry system, designed to send your data wirelessly by email or SMS.
