Calibrating services are available to adjust instruments
and promote proper response from a calibration
laboratory and companies
that provide mobile service. Accuracy is crucial to the proper function
of precision and measurement tools and devices in many industries today.
Thus, the routine calibration of such items is an important part of maintaining
the needed accuracy and quality standards. Calibration is typically accomplished
by measuring the behavior of a specific device with a monitoring instrument,
which allows the calibrator to compare the measured behavior with the
standard at which the device should be. Needed adjustments are then made
to the device until it is back in line with the specified standard for
the instrument.
Instruments that need to maintain a specific unit of measurement to function
properly and instruments that monitor variations of measurement themselves
need to be calibrated regularly. An industrial
scale is an example of a device that monitors weight and after time
will become less accurate due to machine wear. A commercial
oven, used for the mass production of baked goods, also needs
to be calibrated. Lasers,
as well, need to be calibrated regularly in order to maintain the
high accuracy needed to perform their various functions.
Examples of measurements that need to be calibrated in specific devices
are torque, humidity, temperature, pressure, strain, speed, displacement
and mass. The standards for these measurements are defined and agreed
upon by national and international standard organizations, such as
the ISO (International Standard Organization). These standards are
important for local and global trade and ensure ethical practices
within the market. Calibrating services are a necessary bi-product
of these standards.
Although calibrating services are an effective way to increase the
quality of various devices, they are not always one hundred percent
perfect because it is not possible to know every factor that may
affect the calibration process. This uncertainty must always be taken
into account when considering such operations. The possibility of
error is always present even with the most sensitive devices. Furthermore,
the calibration services are only as good as the standards that they
are guided by, so it is important to know exactly what must be done
to generate accurate performance and measurements.
Types of Calibration Services
Calibration is the process through which instruments are adjusted to match measurement standards.
Equipment calibration is
the process through which pieces of equipment are adjusted for precision.
Fiber optic calibration
is calibration that measures light, such as optical power meters. Special
devices that measure optic ranges are used in the calibration of fiber
optic equipment.
Hardness testing
is a type of calibration that tests the hardness and/or tensile strength
of an object.
Humidity calibration
involves the temporary installment of humidity transmitters into a climate
chamber. Humidity calibration involves visual control of the dew point
mirror which may need cleaning; air, nitrogen, helium and another non-explosive
gas may be used during the calibration process.
Instrument calibration is
the process through which instruments are adjusted for precision.
Load cell calibration
is the process of making the measurements of force, torque and weight
as accurate as possible for the load
cell. Much of this calibration is done via computer program.
Pressure calibration
is the testing of pressure instrumentation, such as vacuum wrappers
and sealers, for accuracy.
Temperature calibration
is needed for all devices that monitor and use variance of temperature.
Medical devices, industrial ovens and commercial refrigeration units
are examples of devices that require accurate temperature reading and
output.
Calibration Services Terms
Accuracy –
A tolerance limit that defines the deviation between an output’s
measurement and the actual output.
Alignment – Adjustments that
bring a device to proper operation.

device that creates a continual output reading of the internal input signal.
