產品簡介：

TFW3型(xing)數字(zi)式多功(gong)能土(tu)壤(rang)分(fen)析儀(yi)(yi)(yi)(yi)是在(zai)TFW2型(xing)的基礎上進行(xing)了(le)簡化(hua)，同(tong)TFW2型(xing)一樣，具(ju)有光電(dian)(dian)(dian)比(bi)色(se)分(fen)析、電(dian)(dian)(dian)極(ji)電(dian)(dian)(dian)位分(fen)析、電(dian)(dian)(dian)導分(fen)析和地(di)溫、水溫、氣(qi)溫測(ce)(ce)量(liang)等多種(zhong)功(gong)能。它不(bu)僅能精確測(ce)(ce)試(shi)土(tu)壤(rang)中氮(dan)、磷、鉀、有機(ji)質(zhi)(zhi)的含(han)量(liang)，還可以對土(tu)壤(rang)的酸堿度(du)(du)、鹽分(fen)和地(di)層溫度(du)(du)進行(xing)測(ce)(ce)量(liang)。在(zai)光電(dian)(dian)(dian)比(bi)色(se)分(fen)析中保留(liu)了(le)TFW2型(xing)的濃(nong)度(du)(du)分(fen)析部分(fen)；地(di)溫是單點式測(ce)(ce)量(liang)。該儀(yi)(yi)(yi)(yi)器(qi)即可用(yong)于(yu)農、林、牧、工業(ye)、醫療(liao)衛生、教學(xue)實驗(yan)(yan)等方面的各(ge)種(zhong)常規比(bi)色(se)、PH值、電(dian)(dian)(dian)導、溫度(du)(du)的測(ce)(ce)定，又可用(yong)于(yu)田(tian)間土(tu)壤(rang)養分(fen)速測(ce)(ce)。具(ju)有一機(ji)多用(yong)、方便(bian)直觀，是相關化(hua)驗(yan)(yan)室、農科所、土(tu)肥站和糧、棉、菜、果、花等種(zhong)植(zhi)農戶*的設備(bei)之一。為便(bian)于(yu)野外無交流(liu)電(dian)(dian)(dian)的場地(di)作業(ye)，該儀(yi)(yi)(yi)(yi)器(qi)內配備(bei)了(le)優質(zhi)(zhi)的可充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池，充(chong)(chong)足電(dian)(dian)(dian)后，可提供12小時(shi)左右穩定的直流(liu)電(dian)(dian)(dian)源，免去了(le)無電(dian)(dian)(dian)之憂。另外該儀(yi)(yi)(yi)(yi)器(qi)由(you)于(yu)采用(yong)了(le)高性(xing)能集(ji)成電(dian)(dian)(dian)路(lu)，抗干擾(rao)能力強，數據顯示穩定可靠；測(ce)(ce)試(shi)過(guo)程直觀、方便(bian)。在(zai)光電(dian)(dian)(dian)比(bi)色(se)部分(fen)該儀(yi)(yi)(yi)(yi)器(qi)依據90214274·7號國家設置了(le)對數輸出。
