自動(dòng)便攜SDI測量儀(美國）

YK-Simple SDI

我公司質(zhì)量承諾：一年保修，終身維護(hù)！用專業(yè)精神為您的使用保駕護(hù)航！
污染密度指數(shù)(SDI值)是表征反滲透系統(tǒng)進(jìn)水水質(zhì)的重要指標(biāo)。 
其測定方法的基本原理是測量在 30psi 給水壓力下用 0.45 μ m 微濾膜過濾(間隔十五分鐘)一定量的原水所需要的時(shí)間比值。
但手動(dòng)的SDI測試方法卻極花費(fèi)時(shí)間，而且工作過程非常單調(diào)、容易產(chǎn)生錯(cuò)誤。美國Simple SDI測試儀實(shí)現(xiàn)了自動(dòng)、便攜等特點(diǎn)，而且執(zhí)行SDI5，10，15分鐘100ml及500ml的6項(xiàng)數(shù)值測量。這是手動(dòng)SDI測量方法所不可能完成的

自動(dòng)便攜SDI測量儀(美國）Features:
Performs SDI 5, 10 and 15 minute tests with both 100
ml and 500 ml sample size tests – provides useful data
that’s impossible to obtain with the manual method.
Especially helpful on high SDI waters.
Unattended operation. Start the test and return in 15
minutes for the results – saves you time.
Real-time display of results including SDI, current flow
rate and elapsed time. End of test display includes SDI
5,10 & 15 with 100 ml and 500 ml results.
More accurate than hand testing (ASTM D 4189-95) –
consistent results provides better information.
Battery powered for true portability – conduct tests
anywhere.
Uses standard 47 mm membrane filters – for lower
consumable cost and worldwide availability.
