There are numerous considerations in choosing the correct Elcometer Coating Thickness Quantify/instrument:
1. Is your application on a wet and also dry coating. If it is a wet coating this will be blanketed in a future article
2 . Is your coating on titanium or non-metallic substrate. If it is a nonmetal salt substrate such as wood, plaster, concrete, plastic, rubber or possibly similar then I will cover that in a future article
If your primary application is a dry film coating thickness gauge on a blend substrate then the following questions will pinpoint the correct machine for you.
1 . Is your application in a blasting environment when the substrate is rough or will the application be on some smooth substrate such as in an automotive or powder cover environment. If your application is a rough surface then go on to the next question. We will cover the smooth application in a near future article.
2 . Are you measuring on Ferrous eg Aluminum, Non Ferrous eg Aluminium or on both. This would evaluate if you require an F, NF or FNF unit.
4. Do you require the instrument to download to a desktop computer. If the answer is no then a Basic Model ie H will suffice while if the answer is yes after this you have the choice between: Standard unit – download 1, 900 readings in 1 batch or the Top unit tutorial download up to 150, 000 readings in up to some, 500 batches. The ElcoMaster 2 . 0 software just been launched and comes free with the Standard and even Top models.
4. Do you require an integral ie As i or a separate probe ie S model. An Integral probe is part of the unit and is the more popular model with its you handed operation and its increased robustness. The Separate vertueux model is better for more difficult to access areas or meant for smaller areas where you also have the option of Right Angle, Telescopic together with Miniature probes. You would also be able to use the new Elcometer scan probe if you went for a separate probe option (scan mode only with T model). 5. What height are you measuring? The Scale 1 measures up to 1500 microns, the Scale 2 up to 5mm (5, 000 microns) and also Scale 3 up to 13mm. There are also probes that compare to 30mm. The scan probe also has a Basis 2 probe which can measure to approximately 5mm.
