product number: BS-2022
product name: Air Void Analyzer
type: AVA-3000
specification: ASTM C 457-06
producing area: Denmark
The AVA (Air Void Analyzer) is used to measure the air-void parameters of samples of fresh airentrained concrete.
AVA System Features
Two AVA systems are available: the AVA-2000 and the AVA-3000.
AVA-2000
The AVA-2000 is the daily workhorse, and is based on the original Dansk Beton Teknik (BTK) design from the late 1980s. This model features:
• A complete system, ready-to-use, including a laptop computer with the AVA-2000 software and an installed PCMCIA card with driver software
• Optimized sensitivity of the balance for eliminating the effects of external vibrations during testing
AVA-3000
Recently developed, the AVA-3000 features:
• Latest microprocessor technology with components minimized in size and number
• Only one USB cord connecting 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 tempering of the water and the AVA release liquid for testing. The bath 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 <2 mm (as in the AVA-2000), the AVA-3000 calculates the air-void parameters for chord length <1 mm, as required by the latest ASTM C 457-06 standard
