what is Calibration ?

This refers to the process where you can determine if an instrument or device is producing accurate results within the specified limits when it is compared to traceable standards of measurement. This is important for justifying the processes of Qualification and Validation.
The instrument or equipment with the known accuracy is known as standards.

Calibration Achieves 2 Main Objectives:

1. It checks the accuracy of an instrument
2. It determines the traceability of the measurement

Types of Calibration

1/Pressure Calibration

Pressure calibration is a key function across multiple industries where measurement equipment is used to monitor process performance and safety,

2/Temperature Calibration

In all processed where temperature readings have a critical role, temperature calibration are conducted and are carried out in a controlled environment.

3/Flow Calibration

A Flow meter (or flow sensor) is a test device used to measure linear, nonlinear, mass or volumetric flow rate of a liquid or a gas. The flow rate refers to the speed at which a process fluid is moving through pipelines, orifices, or vessels at a given time and control and instrumentation engineers need to measure this value in order to monitor and regulate the speed and efficiency of industrial flow processes and devices

4/Pipette Calibration

For laboratories that frequently use this measuring instrument, pipette calibration is essential for accurate and precise pipetting results.

5/Electrical calibration

refers to the process of verifying the performance of any instrument that measures or tests electrical parameters such as: voltage, current, resistance, inductance, capacitance, time and frequency.

6/Mechanical calibration

Mechanical instruments are subject to drift due to regular usage, mechanical shock and exposure to varying atmospheric conditions, as such mechanical calibration is needed. During mechanical calibration factors like mass, force, dimension, angle, volume, flatness, torque and vibration are calibrated in a temperature controlled facility.

Purpose of calibration :

To make sure that the readings of equipment or instruments are consistent with other measurements and display the correct readings every single time

To determine the accuracy, precision, reliability and deviation of the measurements produced by all the instruments

To establish the reliability of the instrument being used and whether it can be trusted to deliver repeatable results each time

To map the ‘drift’ as documented. Instruments have a tendency to produce inaccurate measurements over a period of time, following repeated use.

Ensuring that the industry standards, quality assurance benchmarks such as current good manufacturing practice (cGMP) and government regulations are adhered to.
