1.
What is the substrate (the surface material) you are coating
/ inspecting? |
Is the metal a Ferrous Substrate (F) or a Non-Ferrous
(NF)? Sometimes this is difficult to answer จC the
substrate may have already been coated. The easiest way
to identify this is to see if a magnet will stick to the
surface. If it does, then the substrate will be Ferrous,
if it does not, then the substrate is Non-Ferrous.

2. Do
you measure only on this substrate? |
If you only inspect one type of product, then the answer
is yes. If you have a range of products that you
inspect, then you need to consider whether they are all
of the same type of substrate. You should also consider
if you have a future possibility of inspecting other
substrates. If so, you should consider an FN gauge.

3.
What is your Coating / Substrate Combination? |
Ensure compatibility of the coating and substrate;
whether a coating thickness gauge will provide an
accurate reading - see
'What is my Coating/Substrate Combination?'
|
|
4.
Typically, what sort of coating thickness do you need to
measure? |
This will help you to select the correct probe scale
range จC e.g. Scale 1 measures coatings up to 1250µm
(50mils). For other range up to 18000µm, please
specifically inquire TOTAL.

5.
What type of probe do you need? |
Depending on your application you can select
from:
|
• Built-in Probe (the probe is built into
the gauge for accurate single handed
measurements on large surface areas, pipes,
etc.).
|
• Separate Probe (the probe is connected to
the gauge by a cable for all applications).

6. Do
you need to save your readings for your ISO records or as
proof of inspection to your customer? |
TOTAL meter gauges are available in up to three
options:
|
• Basic Gauge จC with simple statistics but
no memory or data output.
|
• Standard Gauge จC with statistics, and data
output (Please order optional accessories:
RS232 or USB cable+software.

7.
What level of accuracy do you need? |
A
key decision on the overall selection of a suitable
coating thickness gauge is how accurate do the readings
need to be? There is a progression from moderately
accurate to very accurate gauges, which is mirrored by
the price of the gauge. In addition the coating
application process and other factors affect the
variability of the coating thickness on a particular
surface and the skill and knowledge of the coating
thickness gauge operator also influences results.
