U23 - Green House

Onset offers high-accuracy, pressure-based water level data loggers for deployment in depths of up to 250 feet in fresh or saltwater wells, streams, lakes, wetlands and tidal areas. These water level loggers feature research-grade accuracy at a great price, and are extremely easy to use, with no cumbersome vent tubes or desiccants to maintain. Stainless steel, titanium and polypropylene models are available.


How It Works




HOBO Water Level Logger (30 ft) - U20L-01
  • Supported Measurements:
    Temperature, Barometric Pressure, Water Level
  • Range: 0 to 207 kPa (0 to 30 psia); approximately 0 to 9 m (0 to 30 ft) of water depth at sea level, or 0 to 12 m (0 to 40 ft) of water at 3,000 m (10,000 ft) of altitude
  • Accuracy: Typical error: ±0.1% FS, 1.0 cm (0.03 ft) water
    Maximum error: ±0.2% FS, 2.0 cm (0.06 ft) water
