SIMPLESDI 2.0 Automatic Portable Silt Density Index Tester

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.

What's New in version 2.0?

After nearly 20 years since the original simpleSDI instrument, we’ve completely redesigned the instrument to make it more reliable, more accurate and added new features.

- New Lithium Polymer battery for more tests per charge, lighter weight and longer life.
- New built-in prefilter to ensure that the flow sensor is protected from particulates.
- New dual pressure regulator design provides safe operation up to 100psi and improves accuracy by regulating the pressure to the test regulator.
- simple SDI uses ASTM D4189-14 compliant .45 micron, 47 mm, MCE membranes for standards compliance and consistent test results.
- simple SDI is housed in a rugged crush-proof case. No flimsy tissue-thin plastic here.
