聯(lián)系我時，請告知來自 儀表網(wǎng)DRL26C樹木生長測量儀
DRL26C 樹木生長監(jiān)測儀用于監(jiān)測樹干的生長微變化，使樹的生長與水分關(guān)系的研究變得更容易和更準(zhǔn)確。傳感器為不銹鋼和防紫外線塑料制作，堅固耐用，適合*監(jiān)測，無須外接電池或太陽能板，內(nèi)置鋰電池和數(shù)據(jù)采集器，可記錄50000個數(shù)據(jù)，通過紅外數(shù)據(jù)輸出。儀器具有較高的分辨率，可精確測量1微米莖桿的微變化，為研究樹木在白天，夜晚等氣候條件差異下的生長提供重要數(shù)據(jù)依據(jù)。
主要優(yōu)點：
? 適用于直徑大于8cm的任何樹干；
? 傳統(tǒng)機械與電子技術(shù)相結(jié)合，測量更準(zhǔn)確；
? 精度較高，分辨率1微米；
? 無損安裝固定；
? 導(dǎo)出數(shù)據(jù)格式為TXT、Excel
技術(shù)參數(shù)：
? 量程：64mm生長量變化監(jiān)測
? 分辨率：0.001mm
