5、數據管理：支持根據時間范圍快速查詢數據，可進行查看、上傳、導出、刪除操作。支持曲線圖和表格2種展示形式，按曲線圖展示時可雙擊放大單圖查看，便于直觀展示數據變化趨勢。
6、數據存儲/導出：本地存儲8G大內存，配置USB接口，支持excel格式文件導出本地/U盤，導出的文件可直接使用無需轉換。數據自動保存：若儀器意外關閉，已測量的數據會自動保存不丟失。
7、配備“數智農業云”平臺：儀器聯網狀態下，可手動將測量數據上傳到物聯網4.0云平臺，用戶登錄賬號即可查看，可在云端對實驗數據進行管理和分析，支持對比分析各項光合指標，支持圖表2種展示形式。
8、設備單機即可使用，含有使用教程視頻，手機掃描二維碼即可查看儀器安裝方式和操作流程等。
9、電池容量大，滿電狀態下野外支持連續使用8小時以上。
10、配置支架，適用于野外一定時間監測，主機支架高度可調，葉室三腳架高度角度均可調，適用不同生長角度的葉片，避免對葉片拉扯造成破壞，無需實驗人員背著儀器，減少人力消耗，擴大使用場景。
