Who We Are

Pyranometer Suppliers

Smis Instrumentation We are Pyranometer Suppliers Suppliers.

A pyranometer is a type of actinometer used for measuring solar irradiance on a planar surface and it is designed to measure the solar radiation flux density (W/m2) from the hemisphere above within a wavelength range 0.3 µm to 3 µm.

The solar radiation spectrum that reach earth surface extends its wavelength approximately from 300 to 2,800 nm. Thermopile pyranometers usually cover this spectrum with a largely flat spectral sensitivity. Photodiode-based pyranometers cover only a portion of the whole spectrum, usually from 400 nm to 1000 nm, and with a less uniformed responsivity.[1]

To make a measurement of irradiance, it is required by definition that the response to "beam" radiation varies with the cosine of the angle of incidence. This ensures a full response when the solar radiation hits the sensor perpendicularly (normal to the surface, sun at zenith, 0° angle of incidence), zero response when the sun is at the horizon (90° angle of incidence, 90° zenith angle), and 0.5 at a 60° angle of incidence. It follows that a pyranometer should have a so-called "directional response" or "cosine response" close to the ideal cosine characteristic.

This pyranometer is widely used in meteorological studies, irrigation scheduling, passive solar system analysis, hydro logic studies and many other environmental studies. This pyranometer is highly appreciated for its sensor calibration, wave length range, stability, sensor housing and accurate data measurement.

From our wide range of pyranometer, we are offering our honorable clients high quality pyranometer. This product is extensively used to collect, analyze & display data from 8 different sources simultaneously for comparing different processes to measure broadband solar radiation on a planar surface and is a sensor that is designed to measure the solar radiation flux density (W/m2). Manufactured at our hi-tech manufacturing unit using superior quality raw material under the guidance of our engineers. Moreover, the entire range undergoes a series of test conducted by quality checkers to ensure its flawlessness. Our clients can avail PYRANOMETER at market-competent prices.
