The ultrasmall infrared probe IRP40.50, with a diameter of only 25 millimeters and a length of 42.4 millimeters, can find a place in any small machining center and leaves sufficient space so that measurement is also possible on the Z axis without a danger of collision. The IRP40.50 is highly precise and is also suitable for small and delicate workpieces with a low probing force of 0.7 N (X/Y). It goes without saying that the m&h IRP40.50 also has the proven HDR infrared transmission.
