SPLite2短波硅辐射传感器

SPLITE2 is a new pyrheliometer developed by the Dutch company Kipp&Zonen for the routine measurement of solar radiation. It has inherited the excellent quality of Kipp&Zonen for decades, and has the advantages of rapid response, small size, reasonable price and easy maintenance. It is suitable for all meteorological conditions and can measure the solar energy value up to the entire hemisphere, which is very suitable for photovoltaic solar product monitoring, crop evapotranspiration assessment, air pollution diffusion calculation and daily teaching.

The SPLITE2 pyrheliometer uses a silicon photodiode sensor/detector to provide a voltage output signal. Thanks to the unique design of the diffuser SPLITE2, the sensitivity changes linearly with the cosine of the incident Angle of the incident light, thus ensuring the accuracy and consistency of the measurement data. Its shape design makes it not easy to form water and easy to clean under meteorological conditions with precipitation.

The SPLITE2 built-in horizontal bubble is easy to level during installation to ensure more accurate and reliable data during operation. At the same time, the two SPLITE2 can also be installed together in a "back-to-back" manner to form a simple albedo measuring instrument. The product is standard with 5 meters of cable, users can also choose 15 meters of cable according to actual needs. In addition, you can equip it with METEON handheld data acquisition and display instrument for on-site measurement and real-time measurement data.
