HOBO Water Temperature Pro v2 Data Logger - U22-001

Water Temperature (400 ft.)

magnifier icon
IMPORTANT: This HOBO data logger requires HOBOware software and a communications device. See compatible items below.

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).

  • Research-grade measurements at an affordable price
  • Waterproof to 120 meters (400 feet)
  • Data readout in less than 30 seconds via fast Optic USB interface
  • Compatible with HOBOware and HOBOware Pro software for logger setup, graphing and analysis
