The LI-200R measures Global Horizontal Irradiance (GHI) - the combination of Direct Normal Irradiance (DNI) and Diffuse horizontal irradiance (DHI). The sensing element measures sunlight in watts per square meter (W/m2) and provides a small current signal that is compatible with any Symphonie series data logger when equipped with a Symphonie® SCM Card.

The LI-200R is an improved version of the popular Li-Cor LI-200SZ Pyranometer. The new sensor has several advantages:

Improved Cosine Response - The new design maintains sensitivity at greater angles of incidence, providing more accurate measurements when the sun is rising and setting.
Improved Cable - A new shielded, twisted cable design replaces the old coaxial cable. It has thicker insulation for improved durability and better sealing.
Improved Connector - New BNC cable connectors have reinforced strain relief to further improve durability.
Removable Cable and Base - The sensor and cable both detach from the sensor base, making it easier to send out for calibration or replace just the cable or just the sensor at your site.
Improved Sensor Housing - More robust water shedding and improved sealing prevent water ingress.

This kit includes a calibration certificate, leveling base, and 2 m (6.6') cable.

Company Details

Wind is one source of energy that is inexhaustible and available for free to all of us.
And at a time when the world is seeking alternative forms and energies, wind power presents itself as a credible
source of energy and fulfilment for the future.
In times when precise and dependable wind power assessment is more important than ever, RK WindMast comes as a fresh new breeze in wind power assessment. Coming from the house of Ramkrishna Iron Works (RKIW) - a specialist organization devoted to designing, manufacturing and supply of integrated environmental wind monitoring systems, RK WindMast promises to introduce ultra-modern technology and powerful wind power assessment tools in India.
RK Wind Mast are certified by reputed institution agencies like IIT BOMBAY, Sardar Patel College of Engineering. The towers are designed and manufactured in accordance with BS EN 61400-12-1 and galvanized as per BS EN ISO 1461
The towers are known to withstand extreme climate conditions. Stringent R&D processes are followed to ensure the stability of the masts as they are tested and certified to perform at peak even at the wind speed of 50m/s. These masts can be installed in the shortest period of time and require only a small piece of land and very small radii to grout guy wire anchor bolts.
With unmatched quality and unbeatable price, RK WindMasts have always maintained numero uno position in wind assessment technology in India. Thanks to its highly trained professions who believe in giving the best every time. RK WindMasts are packed in recycled paper cardboard boxes to enable safe transportation, in the most eco-friendly way.
