A waterproof logger that uses the power of Bluetooth to deliver accurate temperature measurements straight to your mobile device or Windows computer running Onset’s free HOBOconnect app. Designed for durability, this compact logger is ideal for measuring temperature in streams, lakes, oceans, and soil environments. Data collection in the field has never been easier!

Mounting Requirements: It is very important that the logger housing does not get distorted when mounted. When mounting these loggers to any non-flat surface, such as rebar or buoy lines, we recommend using the  included Mounting Boot also useful for mounting loggers so they can be easily removed for service. Additional mounting boots can be purchased as desired.
