What is Calibration?

Calibration is an “operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties and, in a second step, uses this information to establish a relation for obtaining a measurement result from an indication.”(1) Simplified it means calibrations are a direct comparison of a known standard of measurement and the measurement that you are using. 

Why Calibrations are important:

Accuracy is the reason why calibrations are important. Accuracy of a device degrades over time, just as a battery deteriorates with time, so does equipment accuracy. Time isn’t the only factor on equipment; power surges, overloading, and other factors can affect your equipment making it inaccurate.


Why does becoming inaccurate matter?


  1. Inaccurate equipment means that your products are going to be of lesser quality than if it was done with accurate equipment.
  2. Inaccurate equipment can create high amounts of rejected parts that don’t meet a product’s quality standard. These rejected parts mean that you might need to make more parts to replace the rejected ones, resulting in production inefficiencies and costing you mounds of money. Even worse it could result in wasted materials that you have to scrap which can trigger pushbacks of products to customers.
  3. Brand damage, nobody likes brand damage, but it can happen from the continued output of low-quality products. Imagine going to a fancy restaurant that served you boxed macaroni & cheese. You’d be furious with what you were served and might even ask for a refund. This can happen for manufacturers due to inaccurate equipment and bad product output, affecting your brand.
Calibrations why get them

Accuracy leads to quality, quality leads to great products! If you are having inaccuracies with equipment, adjusting your equipment should be a top priority. Calibration services can be done to get your equipment back into peak performance and get your production back on track.   


Calibrations may not seem like a big deal, but they can be the reason that you don’t have a big deal on your hands. The simple act of calibrating can minimize inefficiencies resulting in the longevity of quality products. Preventing inaccurate equipment and low-quality products is the reason for calibrating your equipment, GR Metrology offers accredited calibrations for a huge range of equipment, — view or scope of capabilities.
