Who We Are and What We Do – Calibration Services
This is the first blog posted on the Grand Rapids Metrology website and my first personal blog ever. Being 61 years old and not very tech savvy, I did a little research about blogging before I started. Blogging is essentially the art and science of sharing one’s opinions, experiences, observations, knowledge, etc. on a web site. That’s what we will be doing here!
I am Richard Spruit, CEO of Grand Rapids Metrology, a supplier of measurement products/systems and calibration services with offices in Grand Rapids, Detroit, Benton Harbor, Bay City and Battle Creek. We have been in business since 1922, operating under the name Grand Rapids Scale Company. We have 55 employees and are the largest provider of measuring products/services in the State of Michigan.
In the business, we are what is known as a TSP, third party calibration service provider.
I thought I’d spend my first blog explaining what we mean by calibration services. Calibration is a comparison between measurements—one device of known magnitude or correctness with another device and another measurement made in as similar a way as possible. The known device is called the standard. The second device is the one being tested. When testing or calibrating a scale, the standard is a known test weight. When the standard is placed on the scale, the indication should be of the weight of the standard. If not, it is out of tolerance.
Why is calibration important? It’s important because you tell your customers that the products you produce or sell are of the highest quality, built, designed and sold to the stated specifications and that those products will fit the stated need without adjustment, rebuild or recall. We are in the business of precision. Your product will not be precise unless all the dimensions/specifications are accurate and the product is sold in the stated size/amount. You will only be able to do that if all your measuring devices are and stay accurate. That is why we recommend regular calibration intervals.
The list of items we calibrate includes, but is not limited to, the following:
- Analytical Balances
- Test Weights
- Dial Gages
- Angle Blocks
- Cylindrical Pins
- Cylindrical Ring Gages
- Feeler Gages
- Gage Balls
- Gage Blocks
- Height Gages
- Snap Gages
- Bore Gage
- Optical Comparators
- Thread Plugs
- Thread Wires
- Surface Plates
- Thread Rings
- Torque Devices (up to 1,000 lbs.)
- Torque Wrenches
- Hardiness Testers
- Temperature (RTD)
- Thermal Couplers
If you have devices not on our list, call us. If we can’t handle a specific item, we can get it done at one of our sources.
My next series of blogs will be on specific devices. Next — Torque!
