| Definition | A high-performance research grade pyranometer, which is fully compliant with ISO 9060 Secondary Standard pyranometer performance criteria. The CM21 pyranometer is designed for measuring downward and upward (i.e. reflected) irradiance (radiant-flux, Watt/m2) on a plane/level surface, which results from the direct solar radiation and from the diffuse radiation incident from the hemisphere above. The CM21 houses a second built-in sensing element for temperature compensation. Any change in body temperature, due to thermal shock or temperature gradient effect, is quickly detected by this compensation element, and an offset correction signal is applied to the instrument output signal. The receiving element is coated with a highly stable carbon based non-organic coating, to deliver high quality spectral absorption and long-term stability characteristics. The sensing element is housed under two concentric fitting Schott K5 glass domes. Spectral range is 305 - 2800 nm, sensitivity is 7 - 17 uV/W/m^2, impedance is 50 - 60 ohms, response time is 5 seconds, operating temperature is -40 to 80 degC, non-linearity is less than +/- 0.25% (<1000 W/m^2). | ||
