Presentation: The simplified Aphrometer is designed to check the pressure and the vacuum in the bottles of still awine (Bordeaux bottles, Burgundy bottles).Thanks to its sting this pressure gauge pierces corks and some synthetic corks, but it cannot pierce crown caps or allother metallic shutters. The cork ensures the airtightness. Stainless steel Manometers available: - (-1/+1,5) Bar (default manometer)- (0/4) Bar- (0/6) Bar Needles available: - 2 mm- 2.5 mm- 4 mm Advantages: - Reliable mechanism.- Checks the pressure and the vacuum.- Quality made.- Can check several batches.- Stainless steel manometer.- Customizable aphrometer. NB: Do not hit, do not drop.
