ProScale digital measuring systems are affordable digital measuring devices for making linear measurements with speed, accuracy and repeatability.  Our primary markets are applications requiring measurement accuracy equal to, or better than, a traditional tape measure but not as precise as high accuracy digital measuring systems.  Our digital "fractions to 10 microns" measuring range provides users with repeatable measurement and positioning capabilities with the added benefit of data output and transmission to other devices such as a PC.

A typical ProScale measuring system consists of an extruded aluminum Scale, an Encoder or readhead, and a Digital Readout.  The Scale consists of a series of conductive patterns on a circuit board(s) which is then bonded to the aluminum extrusion.  The Encoder transmits and receives signals to/from the scale to determine it's position.  The Encoder is non-contact and remains captive on the scale so it never requires any adjustment of the measuring 'gap'.   The Digital Readout, many powered by only 2AA batteries, displays measurement information from the Encoder in fractions, decimal inches, centimeters, or millimeters.

Accurate Technology started in Kirkland Washington in 1989. The company's first product was a general purpose measuring system called ProScale Model 100, an incremental capacitive encoder with a custom digital readout. 
In 1996, ATI introduced ProScale Model 150, an absolute capacitive encoder with more readout choices and capabilities.  
In 1997 the founder of ATI retired and it's current owner and president assumed control of the company.  In 1998 ATI moved it's operations to Asheville North Carolina where it designs and manufactures all of its products today. 
In 2007, ATI introduced ProScale Model 180, an incremental inductive encoder that is nearly as robust as the absolute technology, but offers higher sensor movement (speed).
During our 20 year history we have developed many custom and application specific products for the woodworking and quality control markets. Today, many of those custom products, along with 6 different ProScale models are sold worldwide.

Ed Fiantaca, owner and president of ATI remains an active part of the day-to-day operations of the company.  We remain proud that our products are all designed produced in the United States by dedicated quality minded employees.
