Wine Bottle Headspace Pressure
PROBLEM
The headspace pressure inside wine bottles needs to be tested for quality control purposes. A reliable gauge with good accuracy and readability is required. Since it is possible for the bottle to be under vacuum or pressure, a compound gauge is required. Compound gauges are designed to allow the user to read either. Using a pressure gauge for vacuum or vice versa will likely provide false readings and possibly destroy your gauge.
SOLUTIONS
For regular usage in testing wine bottle headspace pressure, a Cecomp DPG1000B±15PSIG-5 is recommended.

The –14.7 psi to 15.0 psig range will cover normal headspace pressure ranges of approximately –3 psi (vacuum) to 3 psi pressure, with zero being ideal. A hollow needle is fitted to the gauge by the winery for testing purposes.
If sparkling wines (at approximately 45 psig) or Champagnes (at 80 to 90 psi) are being tested, a DPG1000B30INHG100PSIG-5 can be specified.

This model will cover all normal vacuum/pressure ranges.
Besides choosing a compound range, you may add a backlight, top port, and either an aluminum or NEMA 4X plastic housing.
