Portable roughness measuring unit SURTRONIC Duo 5 Plus
Application:
handy measuring device suitable for the workshop, in pocket format. Immediately ready for use, simple to
operate, no pre-setting or programming necessary.
Execution:
•2 separately usable units:
– upper part with large LCD display and control keys
– lower part with feed unit and tracing system
– diamond probe R = 5 μm
•infrared interface between both units (distance max. approx. 1 m)
•automatic calibration function
•measurement triggered by push of a button, and immediate display of the Ra value
•display of further parameters, without new measurement of the component
•turns of automatically (sleep function) after 5 min inactivity of the device
•batteries 4 x CR2450
Delivery: display unit with removable feed, integrated probe tip, batteries, metal calibration standard and
carrying case

Surface-roughness reference sample
The comparative inspection of surface quality by visual and tactile examination (finger nail) is carried out according to the standards:
No. 44810 010-120: ISO 4287, ISO 4288, BS 2634 and ANSI B 46.1
No. 44810 200-300: VDI 3345 and VDI 3400

Surface-roughness reference samples
Application: for practical definition and checking of the surface quality of workpieces following metal
removing work by simple visual and tactile comparison (with a fingernail). The reference samples are
wearproof and non-rusting, the galvano-plastic manufacturing method guarantees high precision and
absolute uniformity.
Scope of delivery: set of surface reference samples for the entire range of processing method: horizontal
milling, face milling, longitudinal turning, reaming, flat grinding, lapping
For machining processes
