HOBO Water Level Data Logger Deluxe Kit (100’) - KIT-D-U20-02

HOBO Water Level Data Logger Deluxe Kit (100’) - KIT-D-U20-02



Order Catalog

Description

Combining high accuracy water level measurements with out-of-the-box convenience, this money-saving kit includes everything needed to start logging right away. It is ideal for monitoring water levels and temperatures in wells, streams, lakes and freshwater wetlands, as well as barometric pressure.


Feature

  • 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.
  • Multiple-rate sampling (see demo) allows faster sampling at critical times such as when pumping starts or stops.
  • Available in 4 depth ranges
  • Ideal for use in wells, streams, lakes, wetlands and tidal areas
  • No-vent-tube design for easy reliable deployment
  • Durable ceramic pressure sensor


Spesification

Pressure Sensor
Operation range: 0 to 400 kPa (0 to 58 psia); approximately 0 to 30.6 m (0 to 100 ft) of water depth at sea level, or 0 to 33.6 m (0 to 111 ft) of water at 3,000 m (10,000 ft) of altitude
Factory calibrated range: 69 to 400 kPa (10 to 58 psia), 0° to 40°C (32° to 104°F)
Burst pressure: 500 kPa (72.5 psia) or 40.8 m (134 ft) depth
Water level accuracy*: Typical error - 0.05% FS, 1.5 cm (0.05 ft) water
Maximum error: - 0.1% FS, 3 cm (0.1 ft) water
Raw pressure accuracy**: 0.3% FS, 1.20 kPa (0.17 psi) maximum error
Resolution: < 0.04 kPa (0.006 psi), 0.41 cm (0.013 ft) water
Pressure response time 90%: < 1 second
Thermal response time (90%)†: Approximately 10 minutes in water to achieve full temperature compensation of the pressure sensor

* With accurate reference water level measurement and Barometric Compensation Assistant data
** Absolute pressure sensor accuracy includes all pressure drift, temperature, and hysteresis-induced errors
† Maximum error due to rapid thermal changes is approximately 0.5%.

Temperature Sensor
Operation range: -20° to 50°C (-4° to 122°F)
Accuracy: 0.37°C at 20°C (0.67°F at 68°F)
Resolution: 0.1°C at 20°C (0.18°F at 68°F) (10-bit)
Response time (90%): 3.5 minutes in water (typical)
Stability (drift): 0.1°C (0.18°F) per year

Logger
