Calibration details from the factory are also stored in memory. The MAX-MIN-AVG function allows for the display of maximum, minimum, and average values over any specified time period. Other features include a REL (deviation measurement) function that displays the deviation (positive or negative value) based on measurements at any moment, a HOLD function, and a user-definable auto power-off function. Additionally, the outer circumference of the main unit and the connector area are equipped with a rubber exterior, and the protection rating is IP67.

A measuring instrument that is installed perpendicular to sunlight using a solar tracking device and measures direct solar radiation (W/m²). The LPPYRHE16 has a field of view of 5° and an inclination angle of 1°, in accordance with ISO 9060:2018 and WMO standards. Its operating principle is based on a passive type thermopile sensor. The sensing surface of the thermopile is coated with matte black paint to ensure that the direct solar radiation sensor is not selective to different wavelengths. The spectral range of the direct solar radiation sensor is determined by a quartz window that protects the sensor from dust and moisture. Thanks to the special quartz, non-selective measurements across a spectral range of 200nm to 4000nm are possible. The sensor used achieves a response time faster than what is required for class B direct solar radiation sensors by ISO 9060:2018. (The required response time is 15 seconds according to ISO 9060:2018, while the LPPYRHE16 is under 9 seconds.) ▼ ISO 9060:2018, WMO compliant class B direct solar radiation sensor ▼ Complete overview of solar radiation elements through combined use with an all-sky solar radiation sensor ▼ Long-term high-precision measurements achieved with automatic temperature compensation feature ▼ Calibration certificate included as standard
