植物水勢壓力室——3005
測量(liang)植(zhi)物(wu)葉片(pian)或小(xiao)枝(zhi)條的水勢。將葉片(pian)或小(xiao)枝(zhi)從樣(yang)(yang)本固定器放到(dao)有(you)切割突出頭的樣(yang)(yang)品室(shi),直到(dao)在植(zhi)物(wu)材料(liao)中(zhong)的壓力(li)超過(guo)張力(li)并且開始從切割頭流出葉流,然(ran)后在室(shi)內產生壓力(li),壓力(li)可(ke)(ke)以直接從壓力(li)量(liang)表(biao)中(zhong)讀出。
3005型植(zhi)物(wu)水勢壓力(li)室(shi)帶(dai)一(yi)個(ge)壓力(li)氣罐,特(te)別適(shi)于(yu)田(tian)間使用。硬木樣(yang)(yang)品準備臺被安裝到(dao)重型鋁底盤(pan)上。3005具備多種(zhong)尺寸的密封墊圈(quan)(18-52 cm),可(ke)(ke)保證實(shi)驗過(guo)程(cheng)中(zhong)樣(yang)(yang)品室(shi)的絕對密封。3005可(ke)(ke)提供兩種(zhong)壓力(li)范圍(wei)0-40bar或0-80 bar。
