Temp/RH+ Solar + Soil EC/VWC/Temp Data Logger

The MX2311 pairs research-grade sensing of multiple growing parameters with wireless convenience,
integrating the renowned LI-COR LI-200R pyranometer and LI-300/350 volumetric water content (VMC)/ soil electrical conductivity (EC) sensors that deliver key measurements with scientific-grade accuracy
(calibration uncertainty of ±3% typical).

This all-in-one device captures a comprehensive climate picture, describing the root-zone conditions that
most directly influence water uptake, nutrient movement, plant stress, and irrigation decisions. VWC tells you
whether the root zone has enough water. Soil EC tells you whether dissolved salts in that water are becoming
too concentrated. Combining an external LI-200R pyranometer (measuring total solar irradiance in the
400–1100 nm range) and LI-300 Soil Moisture sensor, along with built-in temperature and relative humidity
sensors, this multiparameter logger enables the calculation of critical metrics such as Accumulated Solar
Radiation (MJ/ m²), Daily Light Integral (DLI of Solar, MJ/m²/day), Vapor Pressure Deficit (VPD, kPa), Electrical Conductivity (EC), Volumetric Water Content (VWC) and Dew Point. Providing laboratory-quality
measurements of solar climate conditions in an affordable, mobile logger, the rugged, battery-powered
MX2311 is easily deployed and expands monitoring capabilities to an even broader range of environmental
and energy applications.

IMPORTANT NOTE: For mounting, an M-PLT and 2003S Leveling Fixture are required. Mounting to poles or pipes require an M-BRK and 2003S.

Users can mount the sensor in the field, and setup and data retrieval are seamlessly simple—no cables or
additional download devices needed using the free HOBOconnect app on your phone or tablet. Effortlessly
configure the logger and download data via Bluetooth (up to a 100 ft range), which allows you to deploy in and
download data from hard-to-reach spots.

Expand your remote monitoring by adding an MX Data Plan, which allows you to upload data to LI-COR Cloud remote software for further analysis, sharing, and more.
