自动便携SDI测量仪(美国） 型号:GS655-Simple SDI库号：M305807 是整套，包含主机，膜片一盒100片，连接管件 标配污染密度指数(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 100ml and 500 ml sample size tests – provides useful datathat’s impossible to obtain with the manual method.Especially helpful on high SDI waters.Unattended operation. Start the test and return in 15minutes for the results – saves you time.Real-time display of results including SDI, current flowrate and elapsed time. End of test display includes SDI5,10 & 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 testsanywhere.Uses standard 47 mm membrane filters – for lowerconsumable cost and worldwide availability.SpecificationsDimensions Inch (mm) Electrical WaterWidth Deep High * Battery: 6V 1.3 AH SLA type. * Pressure: 35-100 psi10.75 (273) 9.75 (248) 5 (127) 13 hours testing/charge. * Temperature: 35-100°F* Power Supply: * Solids: Free of solids.
