surface profile - surface roughness, comparators & pit gauge

Elcometer Home Page

The proper and effective preparation of a surface prior to coating is essential. Making sure that the correct roughness – or profile – has been generated is essential. If the profile is too low, the adhesion of the coating to the surface will be reduced. Too high and there is the danger that the profile peaks will remain uncoated – allowing rust spots to occur.

Elcometer have a wide range of methods for determining the surface roughness, including profile gauges, replica tape, comparators, pit gauges and the stylus method.

Elcometer 224 Digital Surface Profile Gauges*

The Elcometer 224 provides the very latest in surface profile technology. Accurate and user friendly, this surface profile gauge is available with (Elcometer 224 Model T with Bluetooth®) or without memory (Elcometer 224 Model S) and statistics. Memory versions can store up to 50,000 readings in 999 batches.

Elcometer 123 Surface Profile Gauge

This is an easy to use gauge that measures the peak-to-valley height of a blast cleaned surface. The average of a series of measurements provides an indication of the surface roughness and allows the surfaces to be compared as blasting proceeds.

   

Elcometer 223 Digital Surface Profile Gauge

The Elcometer 223 is a battery operated digital surface profile gauge which measures the peak-to-valley height of a surface in a similar way to the Elcometer 123 analogue equivalent, but with the added benefit of a direct RS232 output for data logging.

 

Elcometer 122 Testex Replica Tape

The Elcometer 122 testex tape allows the user to measure the peak-to-valley height of the profile and record it. Testex tape consists of foam with a non-compressible backing. The foam side is rubbed into the surface providing a permanent mould of the profile. The Elcometer 124 Thickness Gauge is then used to measure the peak-to-valley height of the profile formed.

 

Elcometer 124 Thickness Gauge

The Elcometer 124 thickness gauge is used to measure the peak-to-valley height of a surface profile formed in the Elcometer 122 Testex Tape.

 

Elcometer 125 Surface Comparator

Surface comparators allow the estimation of surface roughness by both touch and sight. These simple roughness gauges consist of 4 blasted profiles of varying roughness and are available either in a grit blasted or a shot blasted version.

 

Elcometer 129 Rubert & Rugotest Surface Comparators

Similar to the Elcometer 125, the Elcometer 129 roughness comparators are available in two models: The Elcometer 129 Rubert is available in grit and shot versions whereas the Elcometer 129 Rugotest includes the shot and grit profiles on the same block.

   

Elcometer 127 Keane-Tator Surface Comparator & Magnifier

These comparators from keane-tator are designed to be used with a magnifier. Consisting of 5 blasted profiles on displayed with the roughness value on each disc. In the middle of the disc there is a hole for the comparison to be undertaken using the magnifier. Sand, shot or grit versions available.

   

Elcometer 133 Ships Propeller Roughness Comparators

Similar to the other comparators, the ship propeller roughness comparator have been developed for the specific profiles related to the condition of ships propellers over the life of the propeller. Comparators are also supplied with guidance on the report for Propeller Blades.

 

Elcometer 119 Pipe Pit Gauge

The Elcometer 119 pipe pit gauge is a small pocket sized gauge designed to identify the condition of a pipe. The gauge is placed horizontally on the surface of the pipe and the stylus is positioned into the base of the corrosion pit. The gauge shows the pit depth compared to the nominal pipe wall thickness.

 

Elcometer 7061 MarSurf PS1 Surface Roughess Tester

In protective coating applications there is a requirement to measure surface roughness. Measurements of Surface Roughness are expressed in terms of Ra, Rz or Tp. These values include peak-to-valley profile measurement in combination with an assessment of the frequency of peaks within the sample area. The Elcometer 7061 is a light weight and portable measuring solution for the range of surface roughness measurements required for compliance to International Standards.
