本仪器能自动记录光照时数,连续测定累积光量和测定瞬时照度值。它是农业、林业、气象等部门测定光能的先进仪器。日照是影响农作物生长的重要因素之一。用本仪器来测定日照总量、日照时数和照度,对于开展农业科学实验,探索农作物的生长规律,有很大的意义。一、主要技术指标累积光量测量:0-4000000码(误差在±3％之内)照度测量:400-200000Lux(误差在±5％之内)
The instrument can automatically record the number of hours of light, continuous determination of the cumulative amount of light and determine the instantaneous illuminance value. It is an advanced instrument for measuring light energy in agriculture, forestry and meteorology. Sunshine is one of the important factors affecting crop growth. The instrument used to determine the total amount of sunshine, sunshine hours and illumination, for the conduct of agricultural science experiments to explore the law of crop growth, great significance. First, the main technical indicators Cumulative light measurement: 0-4000000 yards (error within ± 3%) Illumination measurement: 400-200000Lux (error within ± 5%)
