    HOBO® Water Temp Pro v2 Logger

Built to withstand extended periods of immersion, the compact HOBO® Water Temp Pro v2 Logger provides reliable, accurate underwater temperature measurement. The precision sensors and electronics are sealed in a durable case which is waterproof to 100’ and has almost neutral buoyancy for stability in flowing rivers, streams, and tidal estuaries. The logger is less than 5” long, and the low-visibility case keeps the logger hidden from view. An optional high-impact protective rubber boot is ideal for use during times of high water flow or flooding when the logger may come in contact with moving debris. The Water Temp Pro v2 Logger requires an infrared base station (90706) or shuttle (90707) and Hoboware, available as a free download, or Hoboware Pro software (sold separately) for system launch and data retrieval. The associated couplers are included with both the base station and shuttle. In addition, the shuttle can operate as a base station for added flexibility in the field. The high-speed infrared communications offloads data in less than 30 seconds (requires USB port), and the infrared communications port is located opposite the bail end for convenient access while tethered.

    HOBO® Pendant Temp/Alarm One Channel Data Loggers

HOBO® Pendant loggers are waterproof to 30 meters and value-priced for short-term applications or year-long remote deployment. User-selectable sampling intervals can be set from 1 second to 18 hours, and you can program the start time/date or trigger start on-site with a magnet. Fast optic USB interface allows data readout in less than 30 seconds. Logger alarm LEDs flash if temperatures have exceeded user-set levels and delay options, and provide visible verification that temperatures have been within the desired range throughout deployment. The 8K Model stores approximately 6.5K of 10-bit temperature readings while the 64K Model stores approximately 52K of 10-bit temperature readings.

    HOBO® Conductivity Logger for Freshwater

High-accuracy, cost-effective water quality data logger for measuring conductivity and temperature in streams, lakes, and other freshwater sources. Ideal for monitoring aquifers for saltwater intrusion and road and agricultural runoff. Easy to deploy and maintain, features include a non-contact sensor to minimize drift-related measurement errors, open access to the sensor for cleaning, and the HOBOware Pro software enables start/end-point calibration to compensate for any fouling and provides easy conversion to specific conductance and salinity using the Practical Salinity Scale 1978 (PSS-78). USB optical interface provides high-speed, reliable data offload in wet environments. Compatible with the HOBO Waterproof Shuttle for easy and reliable data retrieval and transport. Memory: 18,500 temperature and conductivity measurements when using one conductivity range; 14,400 sets of measurements when using both conductivity ranges (64kbytes). Sample rate: 1 second to 18 hrs, fixed or multiple-rate sampling with up to 8 user-defined sampling intervals. Battery life: 3 years (@ 1 min logging). Maximum Depth: 70 m (225’). Operating Range: -2 to 36°C (28° to 97°F) - non freezing. Weight: 6.82...

    HOBO® Dissolved Oxygen Logger

This precision, self-contained data logger is ideal for measuring concentrations of oxygen in lakes, streams, rivers, estuaries, and coastal waters. Because oxygen concentration is essential for healthy aquatic life, this data logger is a valuable tool for aquatic biologists, hydrologists, and other research professionals. The data logger records up to 21,700 sets of dissolved oxygen and temperature measurements, and the logger utilizes optical dissolved oxygen sensor technology for long-lasting calibration with less maintenance. The optical USB interface allows for high-speed, reliable data offload. Includes data logger, dissolved oxygen sensor cap, protective guard, and calibration boot with sponge. HOBOware® Pro software and an Optic USB Base Station (each sold separately) are required for operation. This logger is also compatible with the HOBO Waterproof Data Shuttle (sold separately), allowing for easy and reliable data transfer and retrieval.

    Onset® HOBO U20L Water Level Logger

This economical, research-grade water level data logger continuously measures the water level and temperature in streams, lakes, wetlands, tidal areas, and groundwater. Featuring a polypropylene housing that withstands use in fresh or salt water, the logger’s non-vented design allows for hassle-free deployment. This standalone logger does not rely on cumbersome vent tubes or desiccant packs for operation, and the durable ceramic pressure sensor withstands freezing. A protective end cap allows for deployment in existing wells or stilling wells. You can select from fixed-rate or multiple logging intervals with up to eight user-defined logging intervals and durations. The logger features an Optical/USB interface, and the HOBO Optic USB Base Station and HOBOware™ Pro software (each sold separately) are required for operation. The Optic USB Base Station allows for communication between the logger and a PC. HOBOware Pro Software provides for easy conversion to accurate water level readings that are fully compensated for barometric pressure, temperature, and water density. An extra water level logger can be used for barometric compensation when needed (one barometric data set can be used...
