Overview

LI200RX-L LI-COR Pyranometer w/Fixed Calibration

The LI200RX pyranometer measures both sun and sky solar radiation with a silicon photovoltaic detector mounted in a cosine-corrected head. The cable contains circuitry that standardizes sensor calibration, allowing complete sensors and cabling to be swapped out in the field without having to change the data logger programming. 

This pyranometer connects directly to Campbell Scientific data loggers and is ideal for agricultural and meteorological applications. The LI200RX is calibrated for natural light. Campbell Scientific does not recommend using the LI200RX under artificial light or plant canopy.

Technical Description

The LI200RX pyranometer monitors sun plus sky radiation. It connects directly to Campbell Scientific data loggers and is used extensively in solar, agricultural, and meteorological applications. This pyranometer includes a completion circuit in its cable that standardizes calibration, allowing complete sensors and cabling to be interchanged without altering multiplier and offset values.

The LI200RX sensor head is calibrated against an Eppley Precision Spectral Pyranometer to accurately measure sun plus sky radiation. Campbell Scientific does not recommend using the LI200RX under vegetation or artificial lights because it is calibrated for the daylight spectrum (400 to 1100 nm).

Benefits

  • Compatible with most Campbell Scientific data loggers
  • Sensor and cable can be swapped out in the field with no changes to the data logger program
  • Ideal for solar, agricultural, and meteorological applications
  • Measures sun plus sky radiation
