自动便携SDI测量仪库号：M305807 自动便携SDI测量仪库号：M305807 污染密度指数(SDI值)是表征反渗透系统进水水质的重要指标。
其测定方法的基本原理是测量在 30psi 给水压力下用 0.45 μ m 微滤膜过滤(间隔十五分钟)一定量的原水所需要的时间比值。
但手动的SDI测试方法却极花费时间，而且工作过程非常单调、容易产生错误。美国Simple SDI测试仪实现了自动、便携等特点，而且执行SDI5，10，15分钟100ml及500ml的6项数值测量。这是手动SDI测量方法所不可能完成的
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.
