產品簡介：

TFW3型數(shu)字式(shi)多功能(neng)(neng)土壤分析(xi)儀(yi)是在(zai)TFW2型的基礎(chu)上進行(xing)(xing)了(le)(le)(le)簡化，同TFW2型一(yi)樣，具有光(guang)(guang)電(dian)(dian)(dian)比色分析(xi)、電(dian)(dian)(dian)極電(dian)(dian)(dian)位分析(xi)、電(dian)(dian)(dian)導分析(xi)和地(di)溫(wen)(wen)、水溫(wen)(wen)、氣溫(wen)(wen)測(ce)(ce)量(liang)(liang)等(deng)多種功能(neng)(neng)。它(ta)不(bu)僅能(neng)(neng)精確測(ce)(ce)試土壤中氮、磷、鉀、有機(ji)質的含量(liang)(liang)，還(huan)可以(yi)對土壤的酸堿度、鹽分和地(di)層溫(wen)(wen)度進行(xing)(xing)測(ce)(ce)量(liang)(liang)。在(zai)光(guang)(guang)電(dian)(dian)(dian)比色分析(xi)中保留了(le)(le)(le)TFW2型的濃度分析(xi)部分；地(di)溫(wen)(wen)是單點(dian)式(shi)測(ce)(ce)量(liang)(liang)。該(gai)儀(yi)器即可用(yong)于農(nong)(nong)、林、牧、工業、醫(yi)療衛生、教學實驗等(deng)方面的各種常規比色、PH值、電(dian)(dian)(dian)導、溫(wen)(wen)度的測(ce)(ce)定，又可用(yong)于田間土壤養分速測(ce)(ce)。具有一(yi)機(ji)多用(yong)、方便直觀，是相關化驗室(shi)、農(nong)(nong)科所、土肥站和糧、棉(mian)、菜、果、花等(deng)種植農(nong)(nong)戶*的設(she)備之(zhi)一(yi)。為便于野外(wai)無交流(liu)電(dian)(dian)(dian)的場地(di)作業，該(gai)儀(yi)器內配備了(le)(le)(le)優質的可充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池，充(chong)足電(dian)(dian)(dian)后(hou)，可提供12小時左右穩定的直流(liu)電(dian)(dian)(dian)源，免去了(le)(le)(le)無電(dian)(dian)(dian)之(zhi)憂(you)。另外(wai)該(gai)儀(yi)器由(you)于采用(yong)了(le)(le)(le)高性能(neng)(neng)集成電(dian)(dian)(dian)路(lu)，抗干擾能(neng)(neng)力強，數(shu)據顯示穩定可靠；測(ce)(ce)試過程直觀、方便。在(zai)光(guang)(guang)電(dian)(dian)(dian)比色部分該(gai)儀(yi)器依據90214274·7號國家設(she)置了(le)(le)(le)對數(shu)輸出。
