Waterproof Data Loggers

HOBO waterproof data loggers are widely recognized as the industry standard for gathering and monitoring water data for months – even years – at a time. They can withstand a wide range of environmental conditions including temperature extremes, rushing rocky streams and ocean storms. Water temperature, water level, dissolved oxygen and fresh water conductivity models are available.

  • U22-001

    Optical Interface for data transferThe HOBO Water Temp Pro v2 is durable with 12-bit resolution. Complete with a precision sensor for ±0.2°C accuracy, this logger measures temperatures between -40°C and 70°C (-40°F to 158°F) in air and up to 50°C (122°F) in water. Its waterproof, streamlined case allows for extended deployment in fresh or salt water. Moreover, the Water Temp Pro v2’s optical USB interface makes it possible  to offload data even while the logger is wet or underwater. A solar radiation shield is required to obtain accurate air temperature measurements in sunlight (RS1 Solar Radiation Shield, assembly required; or M-RSA pre-assembled Solar Radiation Shield).
