Surtronic Duo overview
What it does
The Surtronic Duo is a superior portable surface roughness tester
that measures multiple roughness parameters with a 1-button click.
Roughness measurement parameters Ra, Rz, Rp, Rv, Rz1max, Rsk, Rq
& Rku are displayed on a brightly lit intuitive 2.4” LCD colour display.
Its rechargeable battery operation makes it a convenient way of
performing fast, easy and precise on-the-spot measurements in almost
any environment and surface.
How it does it
The hard-wearing diamond stylus is drawn across the part with a
precision motorised traverse mechanism to ensure that the correct
horizontal distance is travelled.Vertical movement of the stylus is
detected by a high quality piezo-electric pick-up as it travels across
peaks and valleys which converts mechanical movement into electrical
signals.The electrical signal is digitised and sent to a microprocessor
for instant calculation of surface parameters using standardised
algorithms.
Charging
The mini USB port can be used for charging with the included mains
charger (or with any standard USB charger).

Keeping it simple
The Surtronic philosophy keeps the process simple. It is the perfect
tool for any inspector to check surface roughness even in the most
demanding applications.
• Incoming inspections
• Final inspection before shipment
• Process control on the production line
• Checking large components or structures
Standards and traceability
The reference standard supplied can be used both to calibrate the
instrument and check for stylus wear to ensure the most accurate
results are always being achieved.
UKAS calibration and testing
Taylor Hobson provides full certification for artefacts and instruments
in our purpose built ISO graded clean room UKAS facility. Our
UKAS laboratory is able to measure all of the parameters associated
with surface texture, including French, German, USA and Japanese
derivatives.

InstantOn
By utilising InstantOn technology these instruments are ready to
measure in less than 5 seconds from switching on!
In situ measurements
Monitor wear and roughness changes in situ during product’s life. E.g.
monitoring changes in turbine blade roughness as an early warning
sign for defects and efficiency losses.
User-friendly, not user-hostile!
The Surtronic Duo are as simple and easy-to-use as any SmartPhone.
Users have the advantage of the intuitive quick access 3-button menu
and its crisp 2.4” daylight readable industrial colour LCD screen.
Bluetooth connectivity
This next generation bluetooth technology boasts super efficient
connectivity allowing wireless communication between the display
unit and traverse unit.
Built for power…
Powered by heavy duty reliable Li-Poly technology, the Surtronic Duo
operates 24/7 with over 10,000 measurements from a single charge.

Surtronic Duo dimensions
What is a skid?
Surtronic Duo is a skidded device.The skid guides the pick-up along
the workpiece, with the workpiece itself forming the datum for
measurement.This method usually eases set-up by reducing the need
for leveling. It also reduces the effects of vibration due to a much
smaller measuring loop.
The skid is an integral part of the gauge and has a radius large enough
to prevent movement in and out the roughness characteristics of the
surface.The stylus and the skid are independent in their height (Z)
movement but move together in the measurement direction. Surface
deviations are recorded as the difference between the stylus and the
skid movement in the Z direction.
The skid will act as a mechanical filter, taking out much of the general
form of the component. Also, wavelengths greater than the diameter
of the skid will not register.

How much difference does the stylus tip size make?
These instruments use a 5 µm (200 µin) stylus tip radius.This suits
their purpose as a portable tool for checking roughness in three ways:
• Durability – It is less likely to be damaged even when subjected
to mishandling.
• Maintenance – It is easier to remove dirt and oil that collects on
the tip during use.
• Suitability – It acts as a filter to remove the highest surface
frequencies that are more reliably measured in a controlled
environment.
Other Taylor Hobson instruments use a stylus with a tip radius of 2
µm (80 µin).This smaller radius coupled with an inductive gauge head
having low contact force enables analysis of even the smallest surface
imperfections.
