Levelogger 6 Junior
Model 3001
The Levelogger 6 Junior provides an inexpensive alternative for measuring groundwater and surface water levels and temperature. The Levelogger 6 Junior combines a pressure sensor, temperature detector, a datalogger, and a 5-year battery (based on a 1-minute sampling rate) in one compact 22 mm x 160 mm (7/8" x 6.3") stainless steel housing.
The Levelogger 6 Junior records absolute pressure using the same durable Hastelloy® pressure sensor as the Levelogger 6. The Hastelloy sensor performs well in harsh environments and withstands 2 times the overpressure without permanent damage.
The Levelogger 6 Junior’s memory holds up to 75,000 sets of temperature and water level data. It records readings at userdefined intervals from 0.5 seconds to 99 hours. Accuracy is 0.1% FS with lifetime factory calibration.
