Using "Permatol" in testing equipment! Introducing the surface permeability test for concrete.
The test involves installing a chamber on the concrete surface and reducing the pressure to calculate the permeability coefficient from the internal pressure changes, thereby evaluating the density of the concrete surface. The testing equipment used is "Permea-TORR." There is an increasing number of sites using surface permeability tests as a method for quality control of newly constructed structures. 【Features】 ■ Calculates the permeability coefficient from internal pressure changes ■ Evaluates the density of the concrete surface ■ Testing equipment: Permea-TORR *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Testing Procedure】 ■ Perform calibration using warm-up operation and calibration plate. ■ Smooth the concrete surface at the measurement location using a grinding stone or similar tool. ■ Position the chamber cell perpendicular to the concrete surface, ensuring there are no gaps due to surface irregularities. Additionally, when measuring vertical walls or ceiling structures, place a fall prevention device on the cell. ■ Once the measurement start button is turned ON, the measurement will be completed in approximately 5 to 10 minutes. *For more details, please refer to the PDF document or feel free to contact us.
