Rz Rmax Roughness depth DIN 4768
The Mean Roughness depth Rz, is the mean of five roughness depths of five successive sample lenghts Le of the roughness profile.
The maximum Roughness depth Rmax is the largest of the five roughness depths.
Surtronic 25 Surface Roughness Checker
This new edition of the long-standing Surtronic range brings a large display with the simplest of menu structures and the most up-to-date parameters. Its mechanical rigidity and styli have a firm reputation for reliable and repeatable surface finish measurements across a wide range of applications.
The Surtronic 25 is battery powered and offers total portability with a built-in memory capacity (holds up to 100 readings). The instrument can be used either freestanding (on horizontal, vertical or even inverted surfaces) or bench mounted with fixturing for batch measurement and laboratory applications.
Parameter Options to suit your application
The Surtronic 25 an calculate up to 10 parameters according to your measurement
application:
Ra (Arithmetic Mean Deviation)
Rsk (Skewness)
Rz (Average peak to valley height)
Rt (Total height of profile)
Rp (Max profile peak height
Rz1 (Max peak to valley height)
Spacing Parameters (measures the horizontal characteristics of the surface deviations)
RPc (Peak count)
RSm (Mean width of profile elements)
Hybrid Parameters (combinations of spacing and amplitude parameters):
Rmr (Material Ratio)
Rda - Delta a (Arithmetic Mean Slope)
The above parameters cover the most common requirements to check lubrication, feed rates, stresses, friction and wear properties. Additional parameters can be analysed with the addition of Talyprofile software.
Fast Measurement Cycle
The Surtronic 25 incorporates the latest electronics for very fast analysis - results are calculated and displayed even before the traverse unit returns. This fast processing, combined with intuitive menu buttons, greatly reduces measurement cycles.
Intuitive Menu Structure
The Surtronic 25 incorporates a large LCD screen which allows full menu and measurement results to be displayed. Using only two buttons the user can scroll through the menus and make selections intuitively before pressing the MEASURE key. All selections are saved for future measurements. All the measurement criteria and results are displayed clearly on the screen ready to print or export to a PC.
Unique Stylus Lift Mechanism
The Surtronic 25 has a uniquely engineered stylus lift mechanism allows a vertical adjustment of 50mm and rotation of the pick-up to different measuring positions, including right angle or inverted measurements. These adjustments to the height and position of the gauge allow areas and features of a part to be easily measured without additional complex fixturing. This feature saves the operator a huge amount of set up time and allows total flexibility. Typical applications where the stylus lift is invaluable include the measurement of steps, bores, grooves and lands.
Built-in Memory/Storage
No PC or printer cables in your way while you measure - the Surtronic 25 is now truly portable: Take your Surtronic wherever you need to take measurements, save as many batch readings as you need (max 100 measurements) then download to your PC or printer at your convenience.
Optional software is available for PC downloads - code 112/3810-01 including cable.
Long traverse length and extended Pick-up reach
The Surtronic 25 can traverse up to 25mm (or as little as 0.25mm) depending on your component. In addition, the stylus length and pick-up configuration give a long reach, making it an ideal instrument for features such as large and narrow bores. Optional extension rods extend the pick-up further.
Comprehensive Range of Accessories and Pick-ups
Taylor Hobson has developed an extensive range of pick-ups and accessories to suit the varied measurement needs of our customers. In addition to the pick-ups , our applications department regularly designs and manufactures pick-ups and fixturing for specific requirements.
The dimensions of the Surtronic 25 and the pick-ups available are all fully compatible with existing Surtronic 3, 3P and 3+ instruments.
Powerful Software Options
The Surtronic 25 includes an RS232 multi-function port which allows connection of a printer or export of measurement results to a PC for further analysis using the optional Talyprofile software. By setting the Surtronic 25 to "Data Dump" mode, measurements and setup can be instigated directly from the Taylprofile software.
Talyprofile
Advanced surface finish analysis
Talyprofile is a dedicated software package designed for use with workshop or laboratory instruments.
Two versions are available. Talyprofile "Silver" has all functions typically used for a shopfloor inspection. Talyprofile "Gold" has complete laboratory analysis functions.

x indicates availability in Gold or Silver Outstanding graphics The software is visually advanced and provides clear on screen profile images. Talyprofile allows the user to take a basic measurement and create a full measurement report using the software's detailed analysis options and desktop publishing function.
In depth analysis Profiles can be levelled and zoomed to remove unwanted features or defects from the analysis. Distance measurement between features and areas of a profile are easily implemented and the information can be displayed graphically and numerically. Step height and the area of a hole or peak can also be displayed.
Time-saving Analysis Templates A "template" can be created whereby a sequence of analysis functions can be saved and applied to future measurements, turning detailed reporting tasks into routine documents. Desktop publishing facility Talyprofile offers a comprehensive desk top publishing function which allows professional presentation of measurement results and profiles. Graphs, profile and results can be arranged and printed from within the Talyprofile software or copied into other word processing documents giving complete flexibility in reporting.
Full compatability Surface finish results from other Taylor-Hobson surface roughness instruments can be imported to Talyprofile software, allowing a uniform report style to be used throughout your workshop or laboratory.
