The EZ SDI-4™ Automated Silt Density Index Test System is designed to perform a standard Silt Density Index Test according to the ASTM D4189-07. The EZ SDI-4™ will perform four separate tests before filter replacement is necessary. Information is displayed on a back-lit liquid crystal display, and on individual light-emitting diodes (LED). Functions and controls are operated through switches on the membrane keypad.
The EZ SDI-4TM incorporates the following features:
One Temperature sensor to measure temperature change during test.
One Pressure sensor to ensure proper filter feed pressure.
Two Alarm Outputs; one for high or low filter feed pressure, and one for high SDI.
Logs and stores results from previous 64 tests.
