How are Instruments Calibrated
Calibration
compares the measurement values derived by a device by testing it with the
standard calibration result.
The
exact calibration procedure might vary with different products. It generally
involves using the instrument to test samples of one or more known values
called "calibrators."
The
results are used to establish a relationship between the measurement technique
used by the instrument and the known values.
It
is done to determine the instrument's accuracy and ensure its readings.
The
main reason for calibration is to ensure the instrument's reliability and
that it can be trusted.
Measuring
instruments like lux meters, anemometers, Thermo hygrometers, barometers, gas leak
detectors, data loggers, and infrared thermometers are calibrated from time to
keep them up to date.
