Accurate Technology (ATI) manufactures ProScale, ProScaleABS, and other linear measuring devices based on capacitive coupling technology (the same technology used in high accuracy digital calipers).
The company's first product was a general purpose measuring device called ProScale. As the company expanded, the product line grew, with new products added every year. In 1996, ATI introduced ProScaleABS™, an absolute position measuring device. Absolute systems use a more robust and sophisticated method to measure position, resulting in a high immunity to electrical interference and one that does not forget its position.
