Brief introduction: Yaxin-1242 leaf area meter is another portable leaf area meter developed by Beijing Bolun Jingwei Science and Technology Development Co., Ltd. It is more convenient in operation, more rich in measuring parameters and more flexible in function. It can be used to measure the leaves of most common plants in vitro and in vitro, and the special structural design is more suitable for the measurement of long and narrow leaves. In addition to obtaining leaf area, perimeter, length, width and other parameters, the aspect ratio and shape factor are added. Performance and features: 1.Measuring function: it can measure the area, circumference, length, width, length/width ratio and shape factor of the blade instantly. There is no need to calibrate, the uneven leaf margins or wormholes do not affect the measurement results, there is no requirement for leaf color 2.Setting function: set the file name, using English letters, characters and Numbers; Setting display items, you can select and display any measurement items 3.Data view: historical measurement data in the memory of the instrument can be read 4.Calculation function: the cumulative value and average value of leaf area can be calculated 5.Time function: the built-in time and date function of the instrument; The measurement time can be saved with the measurement data 6.Transmission function: USB interface for data transmission; USB adopts no-install driver; Support firmware upgrade 7.System information view: battery voltage information, storage capacity, firmware version and other information can be obtained at any time 8.Power supply function: rechargeable lithium battery, long working time, easy maintenance, safe and reliable 9.Portable function: the whole machine is highly integrated and easy to operate. Suitable for indoor and outdoor use Technical parameters: 1.Sensor: custom contact image sensor 2.Measurement parameters: measuring unit: mm, mm squared Large scan length: over 2m Large effective scanning width: 210mm Scanning speed: 200 mm/s Accuracy of area measurement: less than or equal to 2% (rectangular sample area > 10cm2) Area resolution: 0.1mm2 Length resolution: 1mm Width resolution: 0.1mm Large measuring thickness: less than or equal to 6mm 3.The main machine Display: 128 x 32 dot matrix, 2 lines, Chinese interface display Data storage: 9999 sets of measurement data Interface: usb Power supply: 7V lithium rechargeable battery Power: one charge can scan more than 1000 times Volume: 34 * 6 * 4 (cm) Weight: 1.5 kg Working temperature: 0 ~ 50 ℃.
