TurnCheck™ systems are precision optical instruments designed to measure shafts and other cylindrical parts. Each member of the TurnCheck family is built for ease of use and consistent accuracy, even in difficult shop-floor conditions.  TurnCheck systems are built for the people who use them: With advanced optics, rugged materials, and intelligent controls to make set up and measurements fast, accurate and easy.

OGP TurnCheck™ systems have many features and benefits: 

  • Accurate measurements in shop floor conditions where vibration and temperature variation may not be tightly controlled
  • Rugged baseplate with adjustable vibration damping leveling feet
  • Highly rigid support for the optical motion assembly
  • Extruded aluminum column with an internal lattice
  • Clear, highly accurate images
  • Illumination system produces highly collimated light with a constant wavelength
  • Crisp, uniformly magnified image across the entire field of view, with no edge effects or exclusion zones
  • Receiving optics are fully telecentric with each element designed to eliminate distortion
