Hobo Digital Water Level Longgers
for recording water levels and temperatures in wells, streams, lakes,
wetlands and tidal areas. The HOBO Water Level Logger is a
high-accuracy, pressure based water level recording device that provides
0.1% of full-scale accuracy with a 30' measurement range and better
than 0.1' resolution. Operating as a standalone unit, it does not rely
on cumbersome vent tubes and desiccant packs for operation which
simplifies deployment and eliminates many maintenance issues. The
HOBOware™ Pro software (sold separately) provides easy conversion to
accurate water level readings, fully compensated for barometric
pressure, temperature and water density. An extra water level logger can
be used for barometric compensation when needed (one barometric data
set can be used with all water level loggers in that area). Other
features include an Optical/USB interface, a durable ceramic pressure
sensor, and multiple-rate sampling for 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
distributed through the range.
- Water Level: 0-30' (0-9m), 0-30 psia (0-207 kPa); Temperature: -4°F to 122°F (-20°C to 50°C).
- Water Level: ±0.07 ft. (±2.1 cm); Temperature: 0.67°F at 68°F (0.37°C at 20°C).

for communications between the HOBO Water Level Logger and a PC. Simply
plug the Optic Base Station into a USB port on the PC and the Water
Level Logger into the Optic Base Station. A full Logger offloads in less
than 30 seconds. Operating Range: 32°F to 122°F (0°C to 50°C); 0 to 95%
