Description
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.
Features:
• Low cost
• Robust Hastelloy pressure sensor
• Memory for 75,000 data points with dedicated backup
• 5-year battery life (based on 1 reading per minute)
• Works with all Levelogger 6 Series accessories
• 2X communication speed with new PC Interface Cable
Applications:
• Monitoring water levels in wells and surface water
• Pump and slug tests
• Reservoir and stormwater runoff management
• Watershed and drainage basin monitoring
• Stream gauging, lake and wetland monitoring
• Tank level measurement
