Pressure Calibration
E+E accredited laboratory performs calibrations of measuring devices for absolute, for positive and negative gauge pressure as well as for differential pressure:
Absolute pressure: 0.1…101 bar (1.45...1465 psi)
Relative pressure: -0.9…100 bar (-13...1450 psi)
Differential pressure: -0.3...9 bar (-43.5...131 psi)

Calibration Procedure
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.
