Introduction : S-120 It is more convenient in operation , more abundant in measurement parameters and more flexible in function . It can be used to quickly measure most common plant leaves from ex vivo and non - isolated bodies . Especially the structural design is more suitable for the measurement of long narrow blade . In addition to obtaining the parameters such as blade area , perimeter , length and width , the length and width ratio and shape factor of the blade are also added . Features : The product structure is highly integrated , more portable , high in speed , high in measurement precision , easy to use and easy to maintain . Technical parameters : 1 . Sensor : Customized contact image sensing 2 . Measurement parameters : Measurement unit : mm , mm2 Maximum scanning length : more than 2 m Maximum effective scan width : 210mm Scanning speed : 200 mm / s Area measurement accuracy : less than ± 2 % ( rectangular sample area greater than 10 cm2 ) Area resolution : 0.1mm2 Length resolution : 1mm Width resolution : 0.1 mm Max . thickness : ≤ 6mm
