The Levelogger® 5 LTC logs water level, temperature, and conductivity. It combines a datalogger, 8-year battery, Hastelloy® pressure sensor, temperature detector, and conductivity sensor within a small waterproof housing, 22 mm x 208 mm (7/8″ x 8.2″). A baked-on coating using polymerization technology protects the body against corrosion, abrasion and high temperatures. The conductivity sensor is a 4-electrode platinum sensor, with autoranging capabilities. The minimal-maintenance, sealed Levelogger 5 LTC is simple to clean and calibrate, even in the field.

User-Friendly Operation
Software Calibration and Data Wizards guide you through conductivity calibration and barometric compensation, ensuring accurate data sets. The Data Wizard also converts conductivity readings to Specific Conductance (@ 25ºC).
Levelogger Software allows you to easily program your preferences, download data, and 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; install with direct read cables or wireline/cord suspension. The Levelogger 5 LTC is SDI-12 compatible using the Solinst SDI-12 Interface Cable.
Download data in the field using the Field Reader 5, DataGrabber 5 USB data transfer device, or through Bluetooth® using the Levelogger 5 App Interface and your smart device. Integrate the Levelogger 5 LTC with Solinst Telemetry Systems, which use the latest wireless technologies.
Application of Solinst Levelogger 5 LTC Dataloggers
- 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
- Create a historical database for potable water supply monitoring
- Tracer tests
Biofuel Screen
When a Levelogger 5 LTC is deployed for an extended period, there is the risk of biofouling on the pressure sensor and/or conductivity cell, which can compromise their readings.
The Biofoul Screen is designed to reduce the unwanted buildup of microorganisms, plants, algae, or organisms such as barnacles and mussels, on the sensors. The Biofoul Screen consists of a Delrin sleeve wrapped with copper wire. Slip onto the sensor end of a Levelogger 5 LTC, where it is held in place by compression fit.
Using the natural anti-fouling characteristics of copper, the Biofoul Screen is an affordable option to lengthen the time a Levelogger 5 LTC can be deployed. It reduces site visits and time spent cleaning Leveloggers and improves long-term performance by ensuring accurate sensor measurements.
