Features:
Performs SDI 5, 10 and 15 minute tests with both 100
ml and 500 ml sample size tests – provides useful data
that’s impossible to obtain with the manual method.
Especially helpful on high SDI waters.
Unattended operation. Start the 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.
Battery powered for true portability – conduct tests
anywhere.
Uses standard 47 mm membrane filters – for lower
consumable cost and worldwide availability.
