RizonSDI® Portable SDI
The RizonSDI® portable SDI is fully functional and easy to operate, allowing even non-professionals to quickly master and complete testing tasks with ease and accuracy. In use, the operator only needs to replace the diaphragm, adjust the water pressure to 2.07bar, press the test button to start the test, and the results will soon be displayed on the panel.
Note: The pollution density index SDI value is an important parameter of inlet water quality index of reverse osmosis system, and is the main means to check whether the effluent of the pretreatment system meets the inlet water requirements of reverse osmosis system. Its size is crucial to the operation life of reverse osmosis system.
