Overview of the HOBO™ MX2502 Bluetooth PAR, Tilt & Temperature Data Logger
The Li-Cor HOBO™ MX2502 is a PAR, Tilt and temperature data logger designed for long-term monitoring of Photosynthetically Active Radiation (PAR), Tilt and Temperature in Air and Underwater Environments. Harnessing Bluetooth Low Energy (BLE) technology the MX2502 communicates wirelessly with the free HOBOconnect app on your mobile device or Cloud via the Li-Cor platform. The app makes logger setup, calibration, and data offload quick and easy. The app guides you through the pH calibration process making an otherwise complicated process much easier to follow. This cost-effective compact MX2502 data logger dramatically reduces the time and effort needed to collect field data, and at the same time providing higher resolution data.
