Overview
Featuring high accuracy at a great price and ease-of-use, with no cumbersome vent tubes or desiccants to maintain, this logger is ideal for recording water level and temperature up to 30-ft depths in shallow wells, streams, lakes, freshwater wetlands (stainless-steel), saltwater/brackish wetlands and tidal areas (titanium).
Features
- Lightning protection - no long signal wires, and electronics are shielded in a metal housing
- 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
- Available in four depth ranges
- 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

* Water Level Accuracy: With accurate reference water level measurement, known water density, accurate Barometric Compensation Assistant data, and a stable temperature environment.** Raw Pressure Accuracy: Absolute pressure sensor accuracy includes all sensor drift, temperature, and hysteresis-induced errors.*** Changes in Temperature: Allow 10 minutes in water to achieve full temperature compensation of the pressure sensor. Maximum error due to rapid thermal changes is approximately 0.5%.
