An ISO calibration certificate can be acquired for anemometers. 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 anemometers meets 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 for anemometers 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 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 allowed margin of tolerance
·
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 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 questionss relating to the process of establishing a
calibration interval.
