OVERVIEW
Monitor Temperature and Water Levels with Ease
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:
- U20-001-02 HOBO logger (100′ range)
- BASE-U-4 base station with the required coupler
- BHW-PRO-USB 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 (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

SOFTWARE
HOBOware Software
HOBOware software is used for launching, reading out, and plotting data from HOBO® data loggers. With HOBOware, you can also check logger status, filter and export data, save changes to graphs in project files, and scale data with the Linear Scaling and Pulse Scaling data assistants. There are two versions of HOBOware: HOBOware and HOBOware Pro.
