The HOBO U22 Water Temperature Pro v2 Data Logger 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).
