Product Description:
The Initial Surface Absorption Test (ISAT) Apparatus is a specialized laboratory and field kit designed to assess the water permeability and durability of hardened concrete surfaces. Built in strict accordance with BS 1881 (Part 208), this apparatus measures the rate of water absorption of a concrete surface under a constant pressure head. The complete kit includes a clear acrylic test cap with an integrated watertight seal gasket, a calibrated glass capillary tube assembly mounted on a graduated scale, a water reservoir vessel, and connection tubing. It is indispensable for verifying the quality of precast panels, structural walls, and protective concrete coatings against fluid ingress

Working Principle
Working Principle
The Initial Surface Absorption Test (ISAT) measures the rate at which water is absorbed into the surface of hardened concrete under a constant water head of 200 mm. Water flows through the capillary tube into the test area, and the rate of movement is recorded over time. Lower absorption rates generally indicate denser, less permeable, and more durable concrete.
