Calibration Services & Calibration Service Companies
Calibrating services are performed to measure the reading, or output, of a device and compare it to accepted standards set by the manufacturer and the industry. Calibration devices use electrical signals to calibrate instruments. Once the margin of error has been determined and verified, the device can be adjusted to values identical with the standard in order to maintain a standard, high-quality output.
Calibration is the process through which instruments are measured and adjusted to match accepted measurement standards ensuring precision and accuracy. Measurement standards are normally set by the manufacturer and the industry. Once a margin of error between the devices has been determined, the measurements are adjusted to be identical in order to continue with a standard, high-quality output. Instruments that need to be calibrated require either a field visit from a technician or are sent to a calibration laboratory. Electrical signals are used to calibrate machines, equipment and instruments. Devices dependent on pressure, temperature or speed are calibrated to make sure devices are running efficiently, cost-effectively and up to safety and manufacturers’ standards. Pipette calibration is used in medical and biological laboratory settings while torque wrench calibration is common with the use of nuts and bolts. Load cell calibration helps produce accurate weight measurements and a hardness test determines the hardness of a material in order to examine how well it resists deformation. Almost any component that takes measurements needs to be calibrated at some point. Because accuracy is essential to the performance of measurement tools and devices in many industries, regular calibration is necessary to maintain quality standards and quality assurance. In fact, many industries recommend and require that certain components are regularly calibrated.

Rather than be calibrated at a work site, devices and instruments can be sent to a calibration laboratory for professional service. A pipette, an instrument that is used in a medical setting or for molecular biology, holds and dispenses measured amounts of liquid. It must be calibrated exactly to ensure it is dispensing correct volumes of liquid. This calibration takes place in a laboratory. Pressure calibration is performed on instruments and devices that measure pressure, while temperature calibration is done on temperature-measuring instruments or devices such as a thermocouple or a resistive temperature detector. Speedometer calibration is the process of adjusting speedometers to match industry standards of precision for measurements of speed and distance. The accuracy of a speedometer is important to help car owners drive safely within legal speed limits and also because the speedometer works in conjunction with the car’s odometer. Because torque is the product of force and distance, a torque wrench can be calibrated using an accurately measured weight and a known distance. Torque wrench calibration is common because the tools are widely used for the correct tightening of nuts and bolts. This is important because if a torque wrench incorrectly displays the force it may lead to under-tightening, which does not provide the proper thread loading or over-tightening, which stretches the fastener beyond its limits that may cause it to fail.
A hardness test, which is similar to calibration, determines the hardness of a material. This test examines how well a material resists deformation. Hardness tests are used to investigate strength of a material for a part instead of its performance. Scratches or indentations in the material’s surface identify its key traits and are often unseen with an unaided eye. Because of the wide variety of industrial tools, processes, machines and equipment, different calibration devices are necessary to accommodate them. A load cell is a transducer that converts a force acting upon it into an analog electrical signal. This helps produce accurate weight measurements. Machine calibration is necessary because over time, a machine’s performance degrades due to the wear and tear of industrial use. Vibrations, repetitious movements and pollutants can have a negative impact on the accuracy of machinery; calibration readjusts it. Equipment calibration is a very general category that includes devices, tools and instruments that exert or read measurable amounts of force, energy, current or flow. Instrument calibration makes instruments more precise, which is essential to the performance of measurement tools and devices in many industries. Calibration devices can be handheld, portable or a fixed design. Handheld devices are small, compact and are manually operated. Portable devices, in comparison, are designed to move from one place to another; they may have wheels or handles to add mobility. Fixed instruments are mounted and remain in the same place.
Calibration services have improved greatly since the rise of electronic technology. Sensors and transducers are able to provide measuring techniques that produce precise results better than any previous method. The tools and instruments that require calibration have also benefited through technology and are capable of taking measurements in a variety of locations for a range of specific needs. Before electronic calibration devices, sets of weights were used to estimate loads and perform basic calibrations, but today’s high speed, high performance and high tech equipment requires precise settings and exact numbers. National associations and government-enforced agencies like the National Institute of Standards and Technology promote unity by setting their own standards and requiring that companies regularly maintain and calibrate critical components for safety and consistency reasons. Devices that perform calibration services must be very accurate; otherwise the calibration will be inaccurate. 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 by which they are guided, so it is important to know exactly what must be done to generate accurate performance and measurements.
