Water Level Data Logger
Onset HOBO Logger Measures and Records Water Level and Temperature
 The water level data logger is designed to accurately measure and log water levels and temperatures in wells, streams, lakes, wetlands and tidal
areas. With no cumbersome vents, this logger is completely self-contained. The logger features lightning protection, ceramic pressure sensor, programmable start time and date, data storage up to 21,700 total samples, up to 8 simulataneous sampling rates and a 5 year battery life.
Available in Stainless Steel Housing or Titanium Housing Versions.
Available in 0 to 13ft, 0 to 30ft, 0 to 100ft and 0 to 250ft Depth Versions.
Deluxe Barometric Pressure and Starter Kits Available
Required with the Water Level Data Logger
>> HOBOware™ Software Kit

Water Level Logger Features
- HOBOware™ software provides easy conversion to accurate water level
readings, fully compensated for barometric pressure, temperature
and water density
- Use either a second water level logger or a HOBO
Weather Station for
barometric compensation when needed (one barometric data set
can be used with all water level loggers in that area)
- HOBOware provides comprehensive graphing, analysis and reporting
- No-vent-tube design eliminates installation/maintenance issues and
errors associated with vent tubes, such as bulkiness, desiccant
maintenance, water in tubes, cuts, and decontamination between
deployments.
- Fully sealed housing insures many years of trouble-free operation
- Optical/USB interface for years of reliable data offload in wet environments—no
mechanical or elastomer connectors to fail
- Streamlined housing for snag-free deployment in wells
- Lightning protection—no long signal wires, and electronics are
shielded in stainless steel housing
- Durable ceramic pressure sensor
- Simple wireline mounting makes it easy to hang logger in wells, hidden
from vandals
- Multiple-rate sampling allows faster sampling at critical times such
as when pumping starts or stops
- Includes calibration certificate of accuracy versus NIST-traceable
standards at three pressure points (15, 21 and 29 psia)
- Requires HOBOware Software Kit (PC and MAC Versions) and USB Optic Station
