IAC Geometrical Engineers manufactures a wide range of screw gauge calibration and measuring instruments. Our calibration instruments are used worldwide in the quality inspection industry due to their rapid, flexible, and reliable measurement capabilities. They also comply with many widely used international standards, including GOST, ANSI   /ASME, ISO ,  DIN ,  BS ,  MJ ,  JIS ,  GB ,  Buttress , and API. Our calibration instruments are used worldwide in the quality inspection industry due to their rapid, flexible, and versatile functionality.

MasterScanner's innovative technology is protected from counterfeiting by numerous international patents created by its inventor, Reginald Gallestin.

This innovative instrument sets itself apart from conventional gauge calibration and optical measurement methods in every aspect, including flexibility, time required, setup, measurement, scanning, and data interpretation. Methods using balls and wires are now outdated and unreliable.

The IAC Master Scanner boasts the highest level of precision and minimizes the human intervention required for measurement setup. This allows for the reproduction of highly accurate and reliable measurement results. All screw parameters can be measured in just minutes.

Numerous regulations and standards are incorporated, and test results are obtained in accordance with those regulations and standards. In a single test, all screw parameters at any position can be recorded, and an analysis chart can be displayed that includes the screw curve, related data, and all indication errors required by the regulations.

The parameters for each pitch are as follows:

Basic outer diameter, basic small diameter, simple pitch diameter, virtual diameter, side angle, left angle, right angle, full angle, straightness defects on each side, taper, etc...

International standards:

We compare measured values ​​to all kinds of international standards  : GOST/GB/ISO/BS/ANSI/DIN/MJ/JIS/API/Buttress .

ISO/IEC 17025 certified:

The IAC MasterScanner's 2D scanning method complies with the ISO/IEC 17025 acceptance criteria and is  accredited by accreditation bodies such as RVA, DKD/DAkkS, NIST, A2LA, SCES, DANAK, SWEDAC, UKAS, GOST, NABL, NATA, OAR, and SIT .

Highly regarded in fully automated screw calibration:

IAC lists a great many well-known companies that use MSXP master scanners on a daily basis, including NASA, Boeing, PMC Lonestar, All-American Scale & Calibration, AVIC, Trescal, Baker Gauge, BMW, Envilen Calibrations, Perschmann-Hoffmann Group, Bosch, Tektronix, Volkswagen, JBO, and many others.
