Compteurs d'air entraîné

Air Entrainment Meters are devices designed to measure the air content of fresh concrete using the pressure method. The pressure chamber consists of an air-content measuring unit, a cylindrical body with a capacity of 7 L, a top cover system, an integrated pressure pump, a precision gauge, and valves. The body and cover are manufactured from high-strength cast aluminum. All connections are sealed with gaskets, maintaining calibration stability during long-term field use. The test principle is based on placing fresh concrete into the device at a defined volume and measuring air expansion under a specified pressure differential. After the lid is secured, a test pressure is applied to the system using the integrated pump; when the valve is opened, the air volume stabilizes and the air percentage is read directly from the gauge. A wooden carrying case and tamping rod are available upon request.
