Details: Application: the pollution density index SDI Value is an important indicator of water quality characterization of the reverse osmosis system, the manual SDI test method is extremely time-consuming and the work process is very tedious and error-prone. By Simple SDI will achieve automatic measurement data, to achieve accurate and simple measurement of the daily value of SDI. Simple SDI volume is small, lightweight, battery-powered. Portable, automatically make it an ideal tool for troubleshooting, and day-to-day monitoring of the water system. Features 1. Perform SDI5, 10, 15 minutes 100m and 500 ml of 6 numerical measurement, it provides data manually the SDI amount of methods impossible. It is this feature is particularly important in the performance measurement of high SDI values ??the most prominent. No special operation, the action after 15 minutes after the start of the outcome - saving you time. Real-time display of test results, including SDI and the current flow rate and the time. The last display will be the value of 100 ml and 500 ml SDI5 10,15. 4 microcontrollers and more accurate than manual measurements (ASTMD4189 95) data to provide more useful information. The battery power supply to achieve a truly portable, can be measured in any test. (Use about 13 hours per charge) 6. Using standard 47mm filter membrane, global, and reduce the cost.
