Non-destructive Measurement
仪表测量辐射透射率与两个波长的比率（叶绿素强烈地吸收，近红外，不被叶绿素吸收），使测量无损，几乎瞬时（测量时间小于3秒）。这有助于快速测量多个叶子并随着时间的推移监测相同的叶子。
Storage Capacity and Internal GPS
Memory allocated to data storage allows for 160,000 logged measurements. A mini USB port allows for direct connection to a computer to download data. Chlorophyll meter comes with a standard mini USB to USB cable for data download. New internal GPS allows field data to be geo-referenced. Storage capacity of geo-referenced data is 94,000 measurements.
