自动便携SDI测量仪美国库存库号M305807 自动便携SDI测量仪美国库存库号M305807 

标配：Simple SDI仪 标配主机一台（含膜片1盒100片/盒，在线过滤器1个，滤芯1个，.微孔滤器（含O型密封圈）连接管件

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.
