Q-CheckQ-Check Digital Readout

The Q-Check digital measurement controller by QVI provides full geometric measurement capability with a convenient and simple user control panel.

The Q-Check offers dual backlit, 2-line LCD displays and durable construction that will survive in almost any shop environment. Its full geometric processing power makes quick work of tough measurements.

Q-Check can measure angles, radii, diameters, widths, intersections and included angles, distances, roundness, and straightness. The shop hardened keypad allows selection of Cartesian or polar coordinates, inch or metric units, and absolute or incremental modes. X,Y zero and skew alignment, and recall of previous measurement data are all provided.

Q-Check supports Projectron™ automatic gray-scale edge detection and VidiProbe™ video measurement systems and interfaces with the eCAD® virtual chart gage system.

Q-Touch Digital Readout

Q-Touch DRO

The QVI Q-Touch Digital Readout is an advanced color graphics touchscreen controller offering multi-function geometric measurements and constructions. Q-Touch is compact and offers a bright, easily readable display in all light conditions.

Q-Touch is standard on CCP's CC-14L and CC-16L models.

Quadra-Chek Digital Readouts

Quadra-Chek LogoQuadra-Chek digital readout systems offer full geometric measuring capabilities that Certified Comparator Products can use to update your existing measuring machine with modern capabilities when a new system is not in your budget.

Quadra-ChekCCP has a metrology upgrade package for virtually any optical comparator, profile projector, toolmaker's microscope, or 2-axis measuring machine. We specialize in retrofitting any measuring machine or machine tool with these computers, coupled with Acu-Rite encoders, to give you the edge you need in quality.
