RizonSDI® Portable Automatic SDI Monitor

In order to have some measure of the degree of Suspended solids and colloidal materials in feed water, a concept called Silt Density Index is used. Here a 0.45-micron filter is exposed to the feed water under pressure and filtration rates are calculated.An SDI of less than 5 is considered acceptable for the reverse osmosis systems.

RizonSDI® Portable Automatic SDI Monitor provides following features:

  1. Quick, easy silt density readings that reduce costly and time-consuming manual methods. Push-button calibrated equipment monitors membranes and water quality.
  2. Automatic flow,Time record,No need for stopwatches, graduated cylinders, calculators and tedious labor
  3. With configuration ofrechargeable batteries, superb stand-by time can last up to 25 hours, easily solving field test withoutPower supply problems.
  4. Booster pump added-on cansolve the problem of low site inlet-water pressure or zero pressure.
  5. Power-down protection calendar provides corresponding testing time for each result.
  6. 200 sets of data storage capabilities
  7. Date/Time stamping on every test
  8. Non-volatile memory when the power is down
