Surface Roughness Meters
-
This instrument is compatible with four standards of site to measure surface roughness of various machinery-processed parts, calculate corresponding and clearly display all measurement 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.

Scanning Probe Microscopy/Atomic Force Microscopy (SPM/AFM Analysis)
-
Rocky Mountain Laboratories, Inc.
Scanning probe microscopy (SPM) refers to a family of measurement techniques that utilize a scanning probe. The most common measurement is Atomic Force Microscopy (AFM Analysis), which measures surface topography. Imaged areas can be from the nm scale to as large as 100 µm X 100 µm. Heights and depths of features can be measuredand many surface roughness parameters, e.g Ra, can be calculated. 3-D images can also be produced for dramatic data presentation. Magnetic and electrical response can also be measured with SPM.

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.
