Onset HOBO Pendant MX Temperature/Light Data Logger

A waterproof temperature/light-level logger using the power of Bluetooth to deliver accurate data 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!

Add the MX Gateway. for access to your data in Onset’s cloud-based HOBOlink software (indoor deployments).

Mounting Requirements: It is very important that the logger housing does not become 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 (BOOT-MX2201-2202). This boot is also useful for mounting loggers so that they can be easily removed for service. Purchase additional mounting boots as needed!
