Re: Re: [MW:13290] Surface roughness measurement instruments.

Hi

For measuring surface profile gauge go for

1. Elcometer model 223 Surface profile gauge digital (after blasting)

2. Elcometer DFT model no. 456 for Dry film thickness (after priming /
painting)

3. Elcometer model 319 RH calculator.Dew point to measure dew point ,
surface temp, ambient temp and relative humidity

4. Elcometer model 138 Bresle Set for checking salt contamination.

>Dear Experts,
I work as inspection
Engineer. When i go for Blasting inspection, contractor provided me profile
comparator for surface roughness measurement.
Contractor do Grit blasting in the shop.
I need to measure surface roughness - 75-100 microns Painting system No#1
50-75 microns Painting system No#2

Queries

Q 1: Comparator is enough for surface roughness measurements.
Q2: Is any other tools available for roughness measurement?.
Q3: What is the normal industry practice.


Pl. provide your valuable suggestions as i'm new for painting
activities.

Rao.
