The Solinst Levelogger 5 Junior provides an inexpensive alternative for measuring groundwater and surface water levels and temperature. The Levelogger 5 Junior combines a pressure sensor, temperature detector, a datalogger, and 5-year battery (based on a 1-minute sampling rate) in one compact 22mm x 160mm (7/8" x 6.3") stainless steel housing. The Levelogger 5 Junior records absolute pressure using the same durable Hastelloy pressure sensor as the Levelogger 5. The Hastelloy sensor performs well in harsh environments and can withstand 2 times overpressure without permanent damage. The Levelogger 5 Junior features a memory with a capacity of 75,000 sets of temperature and water level data points. Readings are linear at a user-defined interval between 0.5 seconds to 99 hours. Accuracy is 0.1% FS with lifetime factory calibration. Real Time View option allows immediate viewing of live water level and temperature readings, independent of scheduled programming intervals.
