Onset HOBO KIT-S-U20-01 Offers
Combining high accuracy water level measurements with out-of-the-box convenience, this money-saving kit includes everything needed to start logging right away.
Features
- Lightning protection - no long signal wires, and electronics are shielded in stainless steel housing (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 (use barometric pressure data from nearby weather station)
- Multiple-rate sampling (see demo) allows faster sampling at critical times such as when pumping starts or stops
- Available in four depth ranges
- No-vent-tube design for easy reliable deployment
- Durable ceramic pressure sensor
Applications
- Underwater Research
- River Restoration
- Wetlands Monitoring
- Tidal Studies
- Residential Well Monitoring
- Hurricane Surge Tracking
