Experience high-accuracy environmental monitoring like never before with the MX2308 Temp/RH/PAR Logger. Engineered for precision, this rugged, Bluetooth-enabled device measures photosynthetically active radiation (PAR), temperature, and relative humidity, making it an indispensable tool for growers, researchers, and innovators. From optimising commercial greenhouses to supporting cutting-edge agricultural research, the MX2308 empowers you with actionable data to enhance growth, productivity, and sustainability.

High-accuracy PAR measurement for optimal growth

The MX2308 integrates seamlessly with the LI-COR® 190R PAR sensor, the trusted industry leader in light measurement. Its precision allows you to track PAR levels accurately to optimise photosynthesis and maximise growth in a variety of agricultural and research conditions.

Expand your capabilities with an optional MX Data Plan, which uploads data to the LI-COR Cloud for remote analysis and sharing. This feature is ideal for teams looking to collaborate and gain deeper insights into their data.

Take the complexity out of environmental monitoring with the MX2308 Temp/RH/PAR Logger. Whether you’re managing commercial farming operations or conducting field research, this device ensures you always have reliable, actionable data at your fingertips.

Features
