Product Description

 Introduction 

   MR220 Roughness Meter  is applicable to measure surface roughness of various machinery-processed parts, especially for roughness measurement of complex parts,such as:Flat, Curved surface, Grooves and Holes. Capable of evaluating surface textures with a variety of parameters according to various national standards and international standard. The measurement results are displayed digital/graphically on the LCD, and output to the printer.


 Working Principle 

  Needle scanning method, start the instrument and do the measurement after placing the instrument on the surface of the work-piece. The inside precision driven component of instrument drive the probe slide straightly along the surface of the workpiece while the probe with its sharp stylus detecting the surface of the workpiece. At the same time the workpeice surface roughness will make the stylus displacement along vertically. This displacement makes the probe piezoelectric wafer deform and output electric signal. After amplified and level translated, this signal will go to the data acquisition system.DSP chip will conduct digital filtering and parameter calculation for the collected data. And the measurement results will be displayed on the OLED display screen.

 Optional Items Descrption 

 roughness tester Extending Rod  Extending Rod, extending rod increases the depth for pickup to enter the part. Length of extending rod is 50mm.
 roughness tester Right Angle Rod  Right Angle Rod, change the position of the sensor, mostly use for measure surface of particular groove.
 roughness tester Standard Sensor  Standard Sensor, to measure most of the plane, inclined plane, cone surface, inner hole, groove and other surface roughness, in addition to the standard sensor, other special sensors are needed to measure the measuring platform.  
 roughness tester Curved Surface Sensor  Curved Surface Sensor, to measure smooth cylindrical surface which radius is larger than 3mm, for the large radius smooth spherical surface and other surface also can obtain good approximation, need to work with platform. 
 roughness tester Small hole Sensor  Small hole Sensor, to measure the inner surfaces of holes with radius more than 2mm, better to work with platform.
 roughness tester Deep Groove Sensor  Deep Groove Sensor, measure groove with width wider than 3mm and depth deeper than 10mm, or the surface roughness of step with height less than 10mm, also can used to measure the planar, cylindrical used with platform, better to work with platform.
 roughness tester Metal Substrate Working platform

 Metal Substrate Working platform, adjustable height 200mm.

With flexible and stable operation and wider application range. Roughness of complex

shapes can also be measured. Measurement stand enable the adjustment of the position of stylus to be more precise and measurement to be more stable. If Ra value of measured surface is relatively low, Using measurement platform is recommended.

 roughness tester Marble Substrate Working Platform

 Marble Substrate Working Platform, adjustable height 300mm.

With flexible and stable operation and wider application range. Roughness of complex

shapes can also be measured. Measurement stand enable the adjustment of the position of stylus to be more precise and measurement to be more stable. If Ra value of measured surface is relatively low, Using measurement platform is recommended.
