1、 Overview

The new type of electric waterproof membrane is an instrument used to detect the impermeability of petroleum asphalt paper based felt and elastic full asphalt waterproof membrane. It can meet the test requirements specified in GB328.3-89 and is suitable for GB18242-2000 and GB18243-2000

GBT328.10-2007 GB/T16777-2008/2011 new standard requirements. This instrument uses an electric air pump for pressurization and can be used by departments related to scientific research, construction, production, design and teaching.

This product adopts electrical automatic control for gas pressurization, automatically maintaining pressure, and digital timing, providing great convenience for the detection, testing, and research of the impermeability of asphalt felt and waterproof rolls. When the test pressure is not greater than 0.6Mpa, this instrument can be used to determine the permeability or water permeability of other materials.
