HOBO Water Level Data Logger Deluxe Kit (100’)
$1,690.00 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, as well as barometric pressure.
This kit includes:
- U20-001-02 HOBO data logger (100' range)
- U20-001-04 HOBO data logger (13' range) for barometric pressure
- U-DTW-1 HOBO waterproof shuttle with 5 interchangeable couplers
- U20-CASE-1 carrying case
- HOBOware Pro software
Like other HOBO Water Level Loggers, the 100-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
- 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

-
Typical error - 0.05% FS, 1.5 cm (0.05 ft) water
-
-0.1% FS, 3 cm (0.1 ft) water
-
0.3% FS, 1.20 kPa (0.17 psi) maximum error
