This data logger features high accuracy at a great price and HOBO ease-of-use, with no cumbersome vent tubes or desiccants to maintain. Helpful Links: Sensor location drawing Barometric Pressure Compensation Assistant Demo Multi-rate Sampling DemoHighlighted Features
- Lightning protection - no long signal wires, and electronics are shielded in a titanium housing for use in saltwater (see the Water Level logger sensor location drawing)
- HOBOware Pro software provides easy conversion to accurate water level reading, fully compensated for barometric pressure (see demo) temperature, and water density.
- Multiple-rate sampling (see demo) allows faster sampling at critical times such as when pumping starts or stops.
- Also available in narrow depth range (U20-001-04-Ti)
- Ideal for use in wells, streams, lakes, wetlands and tidal areas
- No-vent-tube design for easy reliable deployment
- Available in stainless and titanium versions
- Durable ceramic pressure sensor
- 3-point NIST-traceable calibration certificate included
