SDI 2.0 Automatic Portable Silt Density Index Tester

The simpleSDI silt density index meter makes Silt Density Index testing so easy that it' s actually a pleasure. The time-consuming manual SDI test with it' s errors and inaccuracies is a thing of the past.

Extremely Accurate: Microprocessor precision plus high resolution flow measurement provides silt density index test accuracy and repeatability far beyond hand testing.
Battery Powered and light weight for true portability. Up to 13 hours of testing between charges.

Performs SDI-5, SDI-10 and SDI-15 tests in both 100ml and 500ml sample sizes for more meaningful silt density index results and a complete picture of filter plugging.
Standards compliant 47 mm membranes for lowest cost, worldwide availability. Our membranes meet the new ASTM D4189-07 standard for silt density index testing.
