Product Description

RizonSDI ^® The portable SDI meter is a professional reverse osmosis SDI testing instrument launched by the company for the Chinese market. It fully meets the water quality conditions, usage habits, and regulatory requirements of the Chinese market. It is specially configured for on-site testing personnel and can meet the needs of various applications, such as ultrafiltration systems, reverse osmosis systems, general water treatment, seawater desalination, laboratories, and on-site operations, etc.

RizonSDI ^® The portable SDI tester has complete functions and is easy to operate. Even non-professionals can quickly master it and easily and accurately complete the testing tasks. During use, the operator only needs to replace the membrane, adjust the water pressure to 2.07 bar, and press the test button to start the test. The results will soon be displayed on the panel.

Note: The pollution density index SDI value is an important parameter of the influent water quality of the reverse osmosis system and is the main means of testing whether the effluent of the pretreatment system meets the requirements of reverse osmosis influent. Its size is crucial to the service life of the reverse osmosis system.
