E+E accredited laboratory performs calibrations of measuring devices for absolute, relative and differential pressure in the ranges:

• Absolute pressure: 0.1...101 bar
• Relative pressure: -0.9...100 bar
• Differential pressure: 0...9 bar

A pressure calibrator is used for the calibration of absolute and relative pressure meters.
The generator consists of a pressure regulating unit, as well as two quartz relative pressure sensors for reference, and a quartz barometer. The pressure drop of a gas stream is measured at a needle valve for the calibration of differential pressures.
