This sensitive pressure gauge from Festo is a practical means of measuring pressure in a vacuum with precision. The device uses ambient atmospheric pressure as a reference or zero point and takes readings in negative values. It has an operating range between -1 bar and 0 bar for very accurate pressure measurements. An additional meter gives readings in 'inches of mercury' (inch Hg) for flexibility. You'll find this type of pressure gauge commonly used in heavy-duty industrial environments.

• Compatible with many types of lubricant for long-lasting performance

• Easy front panel installation style saves you time and energy
• Acrylonitrile butadiene styrene (ABS) housing material for reliable impact resistance

• Heat pumps
• Air conditioning units
• Refrigeration systems

A pressure gauge is designed to read pressure values above atmospheric pressure. A vacuum gauge does the exact opposite and reads values below atmospheric pressure.
