LPT400

The Liquid Permeability Tester (LPT 400) is designed to determine the liquid permeability and the Silt Density Index (SDI) in technical materials in a pressure range between 50 mbars and 4 bars.

A fully automatic program runs the selected test. The liquid is collected in a receptacle and the weight recorded by a balance is automatically transferred to the operating software, which calculates the liquid permeability.

MEASUREMENTS

•Liquid permeability
•Possibility to perform single or up to 3 measurements simultaneously (at one constant pressure level or on varying pressure levels).
•Duration of each cycle: up to 10 min.
•Real time permeability vs time graphic display
•Permeability results are displayed in Darcy and in l/(m2*h*bar)

SILT DENSITY INDEX (SDI)

SDI measures the percent drop per minute in the flow rate of water through a filter, averaged over a period of time.
•In each cycle, the system measures the time required for 500 ml of fluid to pass through the sample, following by sample flushing step for 15 min before starting the next cycle.
•Possibility to carry out up to 12 repeated cycles.
