Surface plates offer essential stability for measuring parts and equipment with tight tolerances. Your quality control department understands the significance of reliable dimensions and equipment. Without them, you can’t guarantee your products will meet customer parameters and legal regulations.
Like other tools, surface plates need periodic testing and inspection to verify that they comply with industry standards and accurately measure your products. At Garber Metrology, we can test, calibrate and inspect granite surface plates for companies in the Mid-Atlantic Region.

Why Is It Important to Calibrate a Flat Surface?
Calibration ensures your surface plates meet flatness specs for your grade, which makes accurate measurements possible. 
Most flat surface plates are granite, and they are instrumental in your quality control department’s precise measurements. Environmental factors, accidents, and other catalysts can make these surface plates uneven, which skews your measurements.
- Wear and tear from testing or abrasions from dust and debris.
- Acidic, abrasive, or other adverse solutions used to clean the plate.
- Direct sunlight and other environmental factors that cause thermal expansion.
- Pools of moisture on the plate.
- Unstable humidity and temperature.
If your surface plate is uneven, your quality control department can’t rely on their measurements. If you ship a product that doesn’t meet industry standards or customer parameters, you may have to issue recalls, raising your production costs.
