Certified High-Accuracy Rulers
Inch
These rulers include a certificate of calibration traceable to NIST with test measurements that confirm accuracy. An economical alternative to Starrett Certified High-Accuracy Rulers, they provide reliable, repeatable measurements. All meet Fed. Spec. GGG-R-791H, which establishes uniform standards for ruler accuracy, graduations, and size. They’re also known as machinists’ rules. They have a corrosion-resistant satin-chrome finish that reduces glare and wear-resistant etched markings. These rulers are labeled with numeric increments that are less than 1" for quick reading.
Flexible rulers are for measuring slightly curved surfaces.
