An ISO calibration certificate can be acquired with our manometers. It includes a control document containing the company
contact details consisting on a laboratory calibration and a certification
to meet ISO standards. This means that manometers meet the
minimum requirements of the national body of measurement and it can be
included in your internal set of measuring instruments. Further information:
Calibration: Control of measurement
magnitudes correction of measuring instruments without the intervention in
the measurement system, or the determination of the systematic display
deviation in relation to the real value of the measuring magnitude.
Calibration document or certificate:
document with the technical properties of the device according to the
national organization of measurement.
Calibration interval: to perform
correct measurements, devices must be calibrated at regular intervals. This
period of time is called calibration interval. It's difficult to
determine this period with accuracy but you should consider the following
factors:
·
Measuring
magnitude and permitted tolerance limit
·
Performance
of the measuring instruments
·
Frequency of use
·
Operating conditions
·
Previous calibrations stability
·
Measuring accuracy required
·
Determining
factors of the quality control systems used by companies
This means that the user is in
charge to check and control the interval between calibrations. We recommend
that this internal between calibrations should be between 1 and 3 years. We
can also offer our expert advice to solve any doubts relating to the process
of establishing a calibration interval.
