Model 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:

The Levelogger 5 LTC includes memory for 100,000 readings of level, temperature, and conductivity, and a 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 50 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.


solinst levelogger 5 junior water level and water temperature datalogger

Model 3001 Levelogger 5 Junior


The Model 3001 Levelogger 5 Junior is designed to be an inexpensive alternative for automatic, continuous water level and temperature datalogging.

The Levelogger 5 Junior operates like the Levelogger 5 absolute datalogger, but has streamlined functions. It uses the same durable Hastelloy pressure transducer as the Levelogger 5, and is calibrated to provide 0.1% FS accuracy. The Levelogger 5 Junior comes in two pressure ranges, 5 m and 10 m (15 ft. and 30 ft. )— excellent for groundwater and surface water applications.

The sealed 22 mm x 160 mm (7/8" x 6.3") stainless steel housing includes the pressure transducer, temperature sensor, 5-year lithium battery, and memory for 75,000 water level and temperature measurements. The Levelogger 5 Junior can be set to record linearly from 1/2 a second to 99 hours.

The Levelogger 5 Junior is compatible with Levelogger Software and accessories, including communication cables, well caps, Solinst Telemetry Systems and SDI-12 Interface Cable. Barologger 5 data can be used to barometrically compensate Levelogger 5 Junior data.
