KIT-S-U20-01
HOBO Water Level Data Logger Starter Kit (30’)
$865.00 USD
Combining high accuracy water level measurements with out-of-the-box convenience, this money-saving kit includes everything needed to start logging right away.
Overview
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.
This kit includes:
- U20-001-01 HOBO data logger (30' range)
- BASE-U-4 base station with 5 interchangeable couplers
- HOBOware Pro software
Like other HOBO Water Level Data Loggers, the 30-foot version offers exceptional value and ease-of-use, with no cumbersome vent tubes or desiccants to maintain.
Features
- Lightning protection; no long signal wires, and electronics are shielded in stainless-steel housing
- HOBOware Pro software provides easy conversion to accurate water level reading, fully compensated for barometric pressure, temperature, and water density (use barometric pressure data from nearby weather station).
- 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
- Durable ceramic pressure sensor
Specifications
Pressure Sensor
-
0 to 207 kPa (0 to 30 psia); approximately 0 to 9 m (0 to 30 ft) of water depth at sea level, or 0 to 12 m (0 to 40 ft) of water at 3,000 m (10,000 ft) of altitude
-
69 to 207 kPa (10 to 30 psia), 0° to 40°C (32° to 104°F)
-
310 kPa (45 psia) or 18 m (60 ft) depth
-
Typical error - 0.05% FS, 0.5 cm (0.015 ft) water
-
- 0.1% FS, 1.0 cm (0.03 ft) water
-
0.3% FS, 0.62 kPa (0.09 psi) maximum error
-
< 0.02 kPa (0.003 psi), 0.21 cm (0.007 ft) water
-
90% < 1 second
-
Approximately 10 minutes in water to achieve full temperature compensation of the pressure sensor
