Solinst Levelogger 6 LTC water level, water temperature, and water conductivity datalogger

Model 3001 Levelogger 6 LTC

Uncompromised Water Quality Data

Continuously log water level, temperature, and conductivity in a single compact instrument. The Model 3001 Levelogger 6 LTC combines a 4-electrode platinum conductivity sensor, Hastelloy® pressure transducer (0.05% FS accuracy), and an 8-year battery into a rugged, corrosion-resistant body built for harsh field environments.

  • 3-in-1 Water Quality & Level Logging:
    Convenient single 22 mm x 208 mm (7/8″ x 8.2″) instrument. Measures level, temperature, and autoranging conductivity from 0 to 100,000 µS/cm with automatic conversion to Specific Conductance (@25˚C).
  • Superior Protection in Harsh & Saline Environments:
    Sealed in a 316L stainless steel body protected inside and out with a baked-on, PFAS-free polymerisation coating and double o-ring seals. Ideal for saltwater intrusion, leachate, and industrial runoff monitoring.
  • 2X Faster Downloads & USB-C Connectivity:
    Double your field efficiency. Full compatibility with the new Mk3 USB-C PC Interface Cable boosts communication speeds to 19.2k Baud for ultra-fast data transfer and easy in-field firmware updates.
  • Zero-Data-Loss Protection & 8-Year Battery:
    Primary non-volatile memory stores up to 100,000 sets of data, reinforced by a dedicated backup memory holding the latest 15,000 readings to ensure critical monitoring records are permanently safeguarded.

Engineered for Long-Term Field Performance

When monitoring complex hydrogeological dynamics—from saltwater encroachment to contaminant plume migration—sensor stability and resistance to biofouling are vital. The Levelogger 6 LTC delivers lab-grade precision with industrial durability.

  • 4-Electrode Platinum Conductivity Sensor: Delivers outstanding autoranging accuracy (+/- 1% from 5,000 to 80,000 µS/cm) with minimal maintenance and simple field calibration using Levelogger Software wizards.

  • Hastelloy® Piezoresistive Pressure Sensor: Exceptional 0.05% FS accuracy across 6 calibrated pressure ranges (5 m to 200 m) with 2 times over-pressure protection.

  • Optional Copper Biofoul Screen: Easily slips over the sensor tip to leverage the natural anti-fouling properties of copper, dramatically reducing bio-buildup from algae, barnacles, and mussels during extended deployments.

  • Advanced Time & Data Management: Full support for local time zones, GMT, and UTC date/time stamps, along with built-in data wizard utilities for automated barometric compensation, data filtering, and file merging.

High Accuracy; Long Battery Life

The Importance of Measuring Drawdown

How Using a Levelogger and 101D Water Level Drawdown Meter Together Provides Essential Data What is Drawdown? Drawdown is a change in groundwater level due to an applied stress, caused by events such as: Pumping from a well Pumping from a neighbouring well Intensive water taking from local area Seasonal declines as recharge rates lower How is Drawdown Measured?
