The CRYSTA-Apex S is a high-accuracy CNC coordinate measuring machine that guarantees
a maximum permissible error of *E0,MPE = (1.7+3L/1000)μm [500/700/900 Series]. Let's
compare the CRYSTA-Apex S with CMMs offering *E0,MPE of approximately (2.5+4L/1000)
µm. If, for example, the required tolerance on a dimension is ±0.02 mm, then the measuring
machine uncertainty should be no more than one-fifth (ideally one-tenth) of that, i.e. 4μm.
This means that with a general-purpose CMM, when the measured length exceeds 14.8"
(375mm), machine uncertainty exceeds one-fifth of the dimension tolerance in this case. In
contrast, as shown in the figure on the right, with the CRYSTA-Apex S the measurement
uncertainty remains within one-fifth of the dimension tolerance up to 30.2" (766mm).
The higher accuracy specification of the CRYSTA-Apex S, therefore, gives it more than
double the effective measuring range in terms of accuracy-guarantee capability in this case.

Air source 7.06CFM (200L/min) CRYSTA-Apex S comes equipped with a temperature compensation system
that guarantees the accuracy of measurement under temperature conditions
of 60.8 to 78.8 °F (16 to 26 °C). From sensors installed on each axis scale and
working in conjunction with sensors placed on the workpiece, temperatures are
obtained before outputting the measurement result to the controller. Thermal
compensation is applied based on 68 °F (20 °C), taking into account the
workpiece material expansion coefficient. The combined axis scale/workpiece
temperature compensation design used on the CRYSTA-Apex S gives superior
results compared to systems with sensors only on the axis scales.
