profilometer

[‚prō·fə′läm·əd·ər]
(engineering)
An instrument for measuring the roughness of a surface by means of a diamond-pointed tracer arm attached to a coil in an electric field; movement of the arm across the surface induces a current proportional to surface roughness.

Noncontact type surface profilometer (Bruker 3D Non-contact profiler) was used for surface roughness measurements.
Surface roughness measurement with the help of surface profilometer revealed that samples treated with blasting with alumina (50[micro]) blasting followed by acid etching with 2% hydrofluoric acid showed the highest mean roughness value.
The latest evolution of WITec's TrueSurface advanced optical profilometer enhances the power and user-friendliness of confocal Raman microscopes.
These studies employed equipment like SEM, profilometer, focus variation microscopy, VHN (with Vickers and Knoop indents) detection and energy-dispersive X-ray spectrophotometry (EDS).
The instrument can also be used as a micro scratch tester, micro wear tester, fatigue tester and high-resolution profilometer.
In addition to the two ART devices on site, the lab will include a profilometer for mapping surface roughness, a spray booth that can handle two full sheets of drywall at one time, and a viewing/ evaluation area with variable integrated lighting (incandescent, CFL, LED) that accommodates a full sheet of drywall.
The dependent variables were the percentage of surface hardness loss (%SHL), as quantitatively evaluated by differences in the mean values of superficial microhardness after treatment, and dentinal wear and roughness, as assessed by the contact profilometer Hommel Tester T1000 (Jenoptik, Schwenningen, Germany).
ASTM International's proposed WK49335, Test Method for Concrete Micro Surface Texture, describes the use of a contact stylus instrument, or profilometer, and reliable data indexes to measure and quantify a slab or structure's smoothness/roughness value.
