HOBO® Water Level Loggers

Water Level Loggers are Completely Self-Contained for Water-Level Measurements

When you need to measure the rise and fall of groundwater, use HOBO Water Level Loggers for high accuracy at a great price. They are famously easy to use, so you can record water levels and temperatures in wells, streams, lakes, wetlands and tidal areas without breaking a sweat. Choose from Loggers with 0-30' (No. 25190), 0-100' (No. 138623) or 0-250' (No. 138624) water depths. Loggers are completely self-contained, so there are no cumbersome vent tubes or dessicants to maintain. They can also be used in air to record barometric-pressure data for accurate compensation when you need it. Simple wireline mounting makes it easy to hang them in wells and out of sight of vandals. Multiple-rate sampling allows faster sampling at critical times, such as when pumping starts or stops. Loggers require HOBO-ware Software (No. 125181) and an Optic USB Base Station (No. 138665) or Waterproof Shuttle (No. 138619) for use.
