Overview of the HOBO™ KIT-D-U20 Series Water Level Data Logger Kit
The Li-Cor HOBO™ KIT-D-U20 series are deluxe prebuilt kits designed for high accuracy water level monitoring. These money savings kits include everything needed to start logging as quickly as possible. The water level data logging kits are ideal for monitoring water levels and temperatures in wells, streams, lakes, and freshwater wetlands as well as barometric pressure. With multiple depth range options there’s a version that’s perfect for each application.
Each water level kit includes a U20-001 in the selected depth range, a U20-001-04 for monitoring barometric pressure, a U-DTW-1 waterproof shuttle with couplers, a U20-CASE-1 protective carrying case, and a copy of HOBOware Pro software.
