用途:

 PlantPen是一反射式儀器, 提供一個方便、低成本測量葉綠素相對含量的方法. PlantPens測量和計算特定的反射指標以評估葉綠素含量、protoprotecting類胡蘿蔔素、以及其他活葉的重要功能.

  • PRI 200 機種   ( 光化學反射指數計Photochemical Reflectance Index)  

兩個窄波段的中心接近531 nm570 nm測量Photochemical Reflectance Index. 胡蘿蔔色素的改變代表光合光的利用效率、二氧化碳的吸收率或者如同缺水逆境這種可靠指標, PRI對此反應靈敏, 因此它是用於植被生產力與逆境的研究.

 

更多精密的PlantPen 機種 (PRI 200-B, PRI 200-S, PRI 200-U, ) 包含藍芽、序列、USB傳輸線三者之一的通信模組.FluorPen1.0軟體提供可視化和數據傳輸例程到電腦.
