A sample is placed in the vial and alcohol is added to free the air. The change in the level of the alcohol in the vial stem indicates the air content. The test takes about 3 minutes to perform and is ideal for field use at either a pour site or batch plant. It may also be used to determine whether more thorough testing may be needed. The open end of the vial has a reinforced lip and extra graduation marks are included on the stem.
The air indicator kit includes a vial with stopper/cup, squeeze bottle for alcohol, brush, and instructions in a plastic case.
