Simple SDI 2000 Automatic Portable SDI Silt Density Index Tester


Simple SDI silt density index meter offers automatic and portable Silt Density Index testing. The Simple SDI microprocessor precision plus high resolution flow measurement guides you through the test process accurately calculates the SDI of the water, eliminating manual calculations and margin of error.

Clear, easy to read LCD display prompts the operator through the test procedure and displays current test data while silt density index tests are underway. Audible alerts notify the operator at the end of the silt density index test as well as if any errors have occurred.

Benefits of Simple SDI Automatic Silt Density Index Tester

  • Routine SDI measurement can prevent membrane fouling and improve the efficiency of RO systems.
  • simple SDI offers automated test process for simpler, easier and accurate SDI measurements.
  • simple SDI is compact, lightweight and battery powered for easy portability.
  • Performs SDI 5, 10 and 15 minute tests with both 100 ml and 500 ml sample size tests – provides useful data which is especially helpful on high SDI waters.
  • Unattended operation. Start the simple SDI 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.
  • Uses standard 47 mm membrane filters – for lower consumable cost and worldwide availability.
