Solinst 3001 Levelogger 5 LTC

The Model 3001 Levelogger 5 LTC, in addition to the Hastelloy pressure transducer and accurate temperature thermistor, has a 4-electrode platinum conductivity sensor. It is ideal for measuring water level, temperature and conductivity during:

• Saltwater intrusion and soil salination studies
• Plume remediation projects
• Leachate monitoring programs at landfills
• Mine tailings monitoring projects
• Water quality programs at waste disposal storage sites
• Agricultural and stormwater (road salt) runoff monitoring
• Water quality initiatives in watershed studies

The Levelogger 5 LTC includes memory for 100,000 readings of level, temperature, and conductivity, and an 8-year lithium battery. The 22 mm x 208 mm (7/8” x 8.2”) stainless steel body has a baked-on finish (inside and out) using polymerization technology for extra corrosion, abrasion, and chemical resistance.

Levelogger Software includes a Calibration Wizard that guides the user through a 1 to 4-point calibration of the conductivity sensor, using standard solutions. The conductivity sensor autoranges from 0–100,000 µS/cm and calibrates from 50–80,000 µS/cm. Accuracy is ±1% from 5,000 µS/cm–80,000 µS/cm and the greater of ±2% or 15 µS/cm from 80 µS/cm–5,000 µS/cm.

The Levelogger 5 LTC can be set to record every 2 seconds to 99 hours, in linear, event-base, or scheduled sampling modes. It is compatible with all Levelogger communication and deployment accessories. A Barologger 5 can be used to compensate the water level readings.
