Everywhere that you look there is a very good chance that you will see some form of gauging, monitoring or detecting device. In your home, in your car, at your work place and in the world surrounding you. Maybe you have wondered just how accurate, or reliable, these devices are. If the owners have used meter calibration services, the answer will be very accurate and reliable.
Some might argue that by fitting a new device, operators would get all the accuracy that they need. Although how long something could justify being classed as new would be open to interpretation. Also the costs of constantly replacing instruments and gauges on a frequent basis could be considered prohibitive.
It is often overlooked that these new devices will also require minor adjustments as they progress along an assembly line. In turn when they get to the customer they will only be set for factory tolerances. Maybe the customer requires a greater degree of accuracy.
It is true that when something has just come from the assembly line everything will be a snug fit. This makes it possible that any tolerances can be set within quite a narrow range. As the device gets utilised components wear against each other, and the fit starts to lose some of that snugness. In effect it broadens that tolerance range. So now more adjustments are needed to keep that level of accuracy.
As a minor illustration consider the water meter in your home and what it does. It measures the quantity of water flowing through it, and records this so that your bill can be calculated. In your neighbor's home is another device doing exactly the same thing. They both have to operate with the same tolerances to make everything even.
The main users for these types of measuring and monitoring devices are industrial concerns. In such places everything is continually measured, monitored and recorded. It all has to be precise, as there is no place for rough reckoning.
Consider the safety aspect of something operating at high temperatures. The end result if things get too hot could often be quite catastrophic. So therefore the operators need to know that the instrumentation and gauges that they are reading will be displaying properly and accurately.
Even when you go to your doctor you can be confronted with devices for measuring things. They take your temperature and then measure your blood pressure. It wouldn't be ideal if those readings were not reliable. If that is just your local doctor's practice, consider how much bigger the concerns would be in a hospital.
Some people might ask about the accuracy of the devices used to calibrate the other devices. Everything is thoroughly checked on a more regular basis. Quite often devices are sent away to an external agency, and here they will be independently checked and verified. So meter calibration services are a lot more involved than people might think. Next time you see a verification label on a gauge or instrument you will have more of an understanding behind how that label got there, and what it signifies.
