Levelogger 5 Junior

Excellent Durability and Reliability.



For important projects with a tight budget, Levelogger 5 Junior provides a cost-effective solution for continuous water level and temperature measurement. It is simple to program with user-friendly software, and easy to deploy with Direct Read Cables or wireline/Kevlar cord and the Levelogger Locking Well Cap. It features a Hastelloy pressure sensor, battery that lasts up to 5 years, and memory for 75,000 sets of readings. Accuracy is 0.1% FS with lifetime calibration. Levelogger 5 Junior is SDI-12 compatible, as is the higher accuracy Levelogger 5.

The 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 22 mm x 160 mm (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 has excellent performance 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 second to 99 hours. Accuracy is 0.1% FS with lifetime factory calibration.
