Description
The Levelogger® 6 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. Double o-ring seals protect against leaks. The conductivity sensor is a 4-electrode platinum sensor, with autoranging capabilities. The minimal-maintenance, sealed Levelogger 6 LTC is simple to clean and calibrate, even in the field.
Features:
- Twice the previous PC interface download speed: using the Mk3 USB-C PC Interface Cable.
- Enhanced electronics: increased stability, sensitivity, and accuracy across temperature ranges
- Large memory: 100,000 sets of data, with dedicated backup memory for 15,000 sets
- Superior protection in harsh conditions: baked-on coating using polymerization, double o-ring seals
- Improved time tracking: stores time stamps, supports multiple time zone displays
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
- Create a historical database for potable water supply monitoring
- Tracer tests
