Hylec Controls - Air Void Analyzer

Samples are taken after concrete has been placed in the structure and consolidated. It provides timely information to reveal problems with the air-void system.

The AVA-3000 features:

• The complete apparatus comprising the base unit, riser column, buoyancy dish, balance, and
  sample collection apparatus.
• Laptop computer with AVA-3000 software.
• Latest microprocessor technology with components minimized in size and number
• Only one USB cord is used to connect the laptop computer and the base unit
• Incorporates a mini balance that can withstand rough treatment during transport and/or testing
• Elimination of the influence of external vibrations on the test results, including the introduction
  of a wind shield positioned on top of the riser column
• Improved stirrer operation with constant rotational speed independent of the load applied on the
  stirrer
• Incorporates a 35-L temperature bath tank for automated de-aerating and controlling the temperatures of the water in the riser column and the AVA release liquid for testing. The waterfilled tank may also function as ballast for stabilizing the base unit
• In addition to the calculation of the spacing factor and the specific surface for chord length less than 2 mm, the AVA-3000 calculates the air-void parameters for chord length less than 1 mm, as required by the current ASTM C457 standard
