The Onset U2000104 HOBO Freshwater Water Level Data Logger (13 ft.) records water level and temperature up to 13 feet depths with no cumbersome vent or desiccants to maintain. The stainless-steel housing is suited for use within shallow wells, streams, lakes, and freshwater wetlands.
- Pressure/Water Level Range: 0 - 145 kPa (0 - 21 psia)
- Temp. Range: -4° - 122°F
- Lightning protection with no long signal wires/electronics shielded in metal housing
- NOTE: This product requires HOBOware software (USB interface cable included with BHW-PRO-CD purchase, ONLY)
- Lightning protection - no long signal wires, and electronics are shielded in stainless steel housing for use in freshwater
- HOBOware Pro software provides easy conversion to accurate water level reading, fully compensated for barometric pressure temperature, and water density
- Multiple-rate sampling allows faster sampling at critical times such as when pumping starts or stops
- Ideal for use in wells, streams, lakes, wetlands and tidal areas
- No-vent-tube design for easy reliable deployment
- Durable ceramic pressure sensor
- 3-point NIST-traceable calibration certificate included

- Environments: For use in outdoor and water environments
- Measurements: Absolute Pressure, Barometric Pressure, Temperature and Water Level
The Onset U20-001-04 HOBO Freshwater Water Level Data Logger, 13 ft. monitors water levels and temperatures in wells, streams, lakes and wetlands (freshwater). With its narrow range this logger provides the best accuracy in shallow waters. This logger offers a great value and easy deployment since there are no cumbersome vent tubes or desiccants to maintain.
Note: U20-001-04 requires the HOBOware software (free to download) to operate, and either a U-DTW-1 Waterproof Shuttle or the Base-U-4 Optic USB Base Station for configuration and data offload. Please also note that a USB interface cable comes with the purchase of a HOBOware Pro CD (BHW-PRO-CD), only.
