    Mounting Requirements

    It is very important that the logger housing does not get distorted when mounted.  For mounting these loggers to any non-flat surface, such as rebar or posts, we recommend using the Mounting Boot (BOOT-MX2201-2201).  This boot is also useful for mounting loggers such that they can be easily removed for service.

  • 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).
