Accurate Data, Easily

Get the measurement accuracy you need – wherever you need it – without having to remove loggers from their deployed locations to offload data. All you need is a mobile phone or tablet running the free HOBOconnect app. No PC software to install, and no cables to connect!


Legendary Reliability

HOBO MX2300 temp/RH loggers are built to withstand the elements. They feature a rugged weatherproof housing designed for long-term studies – even in harsh climates. Their compact size and built-in mounting holes make deployment simple, with no need for mounting brackets in most cases.   Plus, wireless communication means these loggers can be deployed entirely inside our RS1 solar radiation shield for high reliability, while still being easy to offload with a mobile device.


Choice of Models

The HOBO MX2300 Series offers five models, covering a broad range of outdoor monitoring applications, from agricultural research to forest ecology studies. The series includes internal sensor models that are highly durable and easy to deploy and external probe models that are well-suited for monitoring conditions in soils, water, walls, and more. See all Models
