Industry Information

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.


  • Calibration is the process through which instruments are adjusted to match measurement standards.
  • Calibration laboratories are companies that provide calibration services.
  • 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.
  • Speedometer calibration is the process of adjusting speedometers to match standards.
  • 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.
