What are the objective of calibration?

Answer 1

Why calibrate? This is to ensure the veracity of our measurement. How sure are we that the measurement we obtain is true? For a 153.1mm our caliper gives us, how sure are we that it is really 153.1mm and not 153.9mm or 153mm? In order to really know it, we need another instrument of a higher accuracy (standard) and compare its reading with the instrument we have at hand. How far is the correction? By this, we will have an idea about the truthfulness of the measurement our instrument reads. In cases where our reading is far from the true value, we may have to adjust our reading by either adding or subtracting the correction value to the actual value.

The most important aspect of calibration is to have the same reference when refering to something. You can have a block of metal that is exactally one inch long on a side and ask multiple places to measure it and depending on the reference you can get totally different answers. This becomes even more important when talking about a global reference. If you have an item that uses AAA batteries that is made in China you want to know that batteries made in Taiwan are going to fit. The only way this is possible is throught calibration. Engineering a product means absolutely nothing if you cannot build it because the tools used in the production of the item cannot accurately produce the item from worker to worker. Again it is all about having the same reference.

To avoid faults in measurements & bring accuracy in the results; calibration holds utmost importance in the commercial & industrial applications.

Here I am giving some examples to make the importance of calibration clearer;

1. Regular calibration of micro ohmmeters is necessary as these are involved in measuring low resistance levels & control current source in various industrial applications including fuse testing & cable resistance measurement.

2. Most of the times, the determination of safe loads on weighted structures or tensile stress between two ropes or cables is not accurate or show some error; then, cable tension meter certainly needs calibration.

3. If your stopwatch/timer has been old or running slow, then, there may be chances for faulty measurements in your experimental applications. Here comes the need for timer calibration services.

4. Manometers are widely used in an array of industrial applications such as fume hoods to maintain operator safety, liquid storage tanks, pressurized gas, paint booths etc. If your manometer is long overdue for calibration, then, it is the time to calibrate manometer.

5. Temperature-sensitive devices are widely used in the medical & healthcare industries; especially in this COVID-19 impact. Hence, these devices need to be calibrated properly to avoid any fault in measurements and thermal stabilization. For this you should choose efficient temperature calibration services.

If you have the equipment overdue for calibration, then, it's time to reach the calibration service company. Arabcal is one of the popular calibration service company in UAE which performs onsite & lab calibration covering all aspects of industrial verticals.

Calibration is adjusting an instrument or a gunsight to work perfectly
