The GapGun is an easy to use device to measure accurately gaps & flushness. It can take multiple; contact free readings up to ten times faster than conventional methods. The GapGun displays on its coloured touch screen all the measurement results as well as all its functions and menus.


The Gap Gun provides an important improvement in accuracy, repeatability and reproducibility compared to traditional measurement devices like callipers, slip, depth, and taper gauges. The GapGun does not have the disadvantages of these conventional devices, which are open to errors, show inconsistencies between operators, and come in contact with the surface with the possibility of damaging it. The Gap Gun minimizes all these inconveniences with its laser triangulation by Revolution Enhancement Technology (RET). It is a light, hand-held device, which communicates by Wi-Fi with the computer. The operator is free to take measurements within the range of the Wi-Fi system enhancing his/her productivity and efficiency without compromising in accuracy of measurement.


The interchangeable laser heads of the GapGun offer a resolution range from 0.01 to 0.08 mm and a field of view between 7 and 80 mm giving the user wide range gap widths that can be measured (0.1 mm to 50 mm). The SPC3D software supplied with the GapGun is user friendly and provides multiple options of data management and reporting as well as a tool to set up complex and lengthy check plans. These check plans define the sequence of measurements with the appropriate virtual tool and orientation that have to be done on the object. It also guide the operator to the spot where a measurement has to be taken.
