Product Detail

Details

     The HOBO U22-001 Water Temp Pro v2 datalogger computes temperatures between -40°C and 70°C (-40°F to 158°F) in air and up to an astounding 50°C (122°F) in water. The logger comes equipped with ± 0.2°C accuracy. The optical USB interface allows the offloading of data while the logger is wet or underwater. It’s durable, streamlined casing comes with 12-bit resolution adding to the benefit of it being waterproof providing for extended operation in both fresh air and salt water.

     A solar radiation shield is required to acquire precise air temperature measurements in sunlight. (RS1 Solar Radiation Shield, assembly required, or M-RSA pre-assembled Solar Radiation Shield. 

 

IMPORTANT: This HOBO data logger requires HOBOware software and a communications device.

Optical Interface for data transfer.
