Roughness Testers
Roughness is an important parameter when trying to find out whether a surface is suitable for a certain purpose. Rough surfaces often wear out more quickly than smoother surfaces. Rougher surfaces are normally more vulnerable to corrosion and cracks, but they can also aid in adhesion. A roughness tester is used to quickly and accurately determine the surface texture or surface roughness of a material. A roughness tester shows the measured roughness depth (Rz) as well as the mean roughness value (Ra) in micrometers or microns (µm). Measuring the roughness of a surface involves applying a roughness filter. Different international standards and surface texture or surface finish specifications recommend the use of different roughness filters. For example, a Gaussian filter often is recommended in ISO standards.

Rope Testers
The LMA Signal measures loss of metallic cross-sectional area (LMA) caused by corrosion, abrasion, etc. The LMA Signal is quantitative and can be calibrated. (Typically, a rope must be retired when the LMA exceeds 10%).The WRR Signal measures wire rope roughness (WRR). WRR is defined as the aggregate surface roughness of all wires in a rope. WRR is typically caused by and indicates internal and external corrosion pitting, broken wires and clusters of broken wires. The WRR signal is quantitative, and it is calibrated together with the LMA Signal.The LF Signal can indicate localized flaws (LF), for example, broken wires, corrosion pitting, etc. Because it is only qualitative - and cannot be calibrated - it is of limited value for assessing rope deterioration and for making rope retirement decisions.

Roughness Tester
Compatible with four standards of site to measure surface roughness ofvarious machinery-processed parts, calculate corresponding and clearly display allmeasurement parameters. When measuring the roughness of a surface, the sensor is placed on the surface and then uniformly slides along the surface by driving the mechanism by the sharp built-in probe. This roughness causes displacement of the probe which results in change of inductive amount of induction coils so as to generate analogue signal, which is in proportion to the surface roughness at output end of phase-sensitive rectifier.

Optical Profilers
Finally, measurements of surface roughness and topography can be made for a price that's less than that of a stylus profilometer. The Profilm3D has sub-nanometer vertical resolution, which surpasses optical profilometers that cost 3x as much. It does so by using the same state-of-the-art measurement technologies as the most sensitive optical profilers available: vertical-scanning interferometry (VSI) and phase-shifting interferometry (PSI).

SURFACE PROFILE GAGES
Steel is often abrasive blast cleaned or otherwise roughened prior to painting. The peak-to-valley height of the resultant surface profile is an important factor in the performance of applied protective coatings. Low profile may reduce coating bond strength (adhesion). Too high and the peaks may receive insufficient coverage and possibly rust prematurely. The costly application of more coating may be required if the profile is too high. For these reasons, surface profile should be measured prior to coating application to ensure that it meets contract specifications.
