The Accreditation Scope Values
The pressure ranges are 5 Pa to 100 MPa in pneumatic systems. A pneumatic pressure balance is used as a reference standard.
Absolute and gauge pressure measurements up to 7 MPa can be realized using the automated mass handled calibration system in our pressure laboratory. Calibrations are automated using software.
A Force Balanced Piston Gauge (FPG) system is used in gauge, absolute and absolute differential operation in the range of 1 Pa-15 kPa in our pressure laboratory.
The barometric chamber and measurement system works in the range of 200 mbar a.-1040 mbar a for the barometer calibration process.
Hydraulic pressure measurements are realized in the range of 8x105 Pa to 500 MPa.
Dynamic and semi dynamic pressure measurements can be realized using the drop weight method.
