用途：PlantPen系列植物PRI & NDVI計是一款小巧的快速測量植物反射光譜指數的野外便攜式儀器，可根據反射系數確定植物特征。通過各種反射系數可以評定葉綠素含量，和其他重要的特征。有兩個標準版本光化學反射系數（Photochemical Reflectance Index，PRI）和歸一化植被指數（Normalized Difference Vegetation Index，NDVI）。整合了藍牙技術（藍牙模塊或USB軟件狗），FluorPen 1.1軟件提供可視化操作和數據傳輸到PC上。根據用戶需要，還可提供定制服務。

兩種標準版本：

■PRI 210植物光化學反射系數計：在531nm~570nm波段之間測定葉反射系數。該參數對類胡蘿卜素極為敏感，反應植物的光合作用中的光能利用效率和CO2同化速率，并可作為植物水脅迫的可靠指數。因此廣泛用于植物產量和脅迫研究。

■NDVI 310植物歸一化植被指數計：用來測定NDVI（一種植物體葉綠素重要的指標），在660nm~740nm波長處比較反射光。葉綠素會強烈吸收紅光用于光合作用，而葉片細胞結構會強烈反射近紅外光。因此，NDVI與光合能力直接相關，從而反映植物冠層的能量吸收狀況。

應用領域：

快速測量葉綠素含量

植物光合研究

早期脅迫檢測

氮素利用效率研究

功能特點：

攜帶方便、操作簡單。

直接無損測量得到NDVI和PRI值。

內置藍牙與USB雙通訊模塊，GPS模塊，輸出帶時間戳的地理位置

軟件可導出數據為Excel格式，具備實時控制和遙控功能。

可用于農業(yè)、林業(yè)以及植物學中光合作用、逆境脅迫等的研究和教學。
