           This is a research grade normal incidence direct solar irradiance sensor (also known as a pyrheliometer). Suitable direct solar irradiance measurement of the sun. This is a First Class compliant pyrheliometer, as per the latest ISO and WMO standards.

            The foreoptic assembly feature a precision ground and polished quartz window/lens, For true special solar transmission ranging from 0.2 – 0.4 m. As per the latest ISO-9060 and WMO standards, the fully opening view angle is collimated precisely to 5.0° degrees, making the sensor ideally suited for normal incidence direct solar irradiance measurement. Capable of measuring up to two suns, 2000W/m2 , the pyrheliometer can be deployed anywhere on earth. The instrument employs a passive thermopile-based sensing technology that generates a low level DC millivolt output signal proportional to the normal incident direct solar flux received at  the detector surface. Also features a thermally isolated low power window/lens heater in the foreoptic, when cycled on/off prior to sunrise the heater effectively eliminates the formation of dew on the pyrheliometer  thus resulting in improved post sunrise early morning measurements applications include scientific meteorological/climate observation, material testing research, solar collector/PV panel efficiently and solar renewable resourse assessment. The signal cable can be easily replaced by the user onsite, thus minimizing down-time and expense otherwise associated with instrument re-cabling and/or cable connector replacement by the manufacturer.
