Hobo Digital Water Level Longgers

Ideal 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.

Specifications: Range
- Water Level: 0-30' (0-9m), 0-30 psia (0-207 kPa); Temperature: -4°F to 122°F (-20°C to 50°C).  

Accuracy
- Water Level: ±0.07 ft. (±2.1 cm); Temperature: 0.67°F at 68°F (0.37°C at 20°C).
 

Resolution
- Water Level: 0.007 ft. (0.21 cm); Temperature: 0.1°F at 68°F (0.1°C at 20°C).

Optic USB Base Station
-
Required 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% RH, non-condensing, non-fogging.
