Calibration defines the accuracy and quality of measurements recorded using a piece of equipment. Over time there is a tendency for results and accuracy to ‘drift’ when using particular technologies or measuring particular parameters such as temperature and humidity. To be confident in the results being measured, there is an ongoing need to maintain the calibration of equipment throughout its lifetime for reliable, accurate and repeatable measurements.

To assure accuracy in instrument calibration, it is vital to ensure that each component of the measuring instrument is conforming to its specified standard. Regular equipment calibration carried out in a set format helps you obtain valid data and operate in a safe working environment.

The goal of calibration is to minimize any measurement uncertainty by ensuring the accuracy of test equipment. Calibration quantifies and controls errors or uncertainties within measurement processes to an acceptable level.


Temperature calibration refers to the calibration of any device used in a system that measures temperature. Most importantly, this usually means the temperature sensor, itself, which is typically a platinum resistance thermometer, thermistor, or thermocouple.


The high reliability of electronic measuring instruments such as sound level meters enables to make accurate measurements after a simple check with acoustic calibrators. In many cases this check is also carried out after each measurement to validate the results. To make sure an instrument is working correctly, more comprehensive checks are required periodically making the portable acoustic calibrators an excellent choice for making highly accurate, in-field calibration of your measuring instrument.
