BENEFITS DEMO CONTACT   Welcome to HELIMETRIC - a revolutionary diameter measurement tool for use by professionals from quality control, production and sales to acquire highly repeatable, mathematically accurate measurement of round products. In the manufacture of round products, dimensional accuracy is critical. As technology and value of cylindrical components increase, so does the need for precise measurement. Better diametrical control means less waste and superior quality. The HELIMETRIC sheet gage is designed specifically to address this challenge. HELIMETRIC gages are accurate, easy-to-use, and cost-effective diameter measurement devices. A precise sheet of stainless steel is rolled into a cylinder to fit around or inside the surface to be measured. The ends of the sheet are marked in scale increments and meet helically to form a sliding scale.
