CMI 233 : Material Coating Thickness Gauge

The CMI233 gauge provides a reliable means for performing accurate, efficient inspection of coating/plating thickness at the lowest cost. Measurements can be taken in automatic or continuous modes. A scanning option compensates for uneven or textured substrate materials, enhancing performance of gauge repeatability and reproducibility. A large memory capacity for over 12,000 readings can accommodate even high usage applications.

The CMI233 package enables control of plating and paint & powder coating processes using advanced magnetic induction and eddy-current technology. The CMI233 material coating thickness gauge provides non-destructive coating thickness measurement for non-magnetic coatings over magnetic (ferrous) substrates and non-conductive coatings over conductive substrates (primarily Al, Cu as close to 100% IACS conductivity is required). The system was specially designed to handle the needs of platers, coaters, and quality professionals. Three versions of the CMI233 material coating thickness 13gauge can be purchased:

CMI233E: Instrument, ECP eddy current probe, protective case and set of NIST traceable calibration shims.

CMI233M: Instrument, SMP-2 magnetic induction probe, protective case and set of NIST traceable calibration shims.

CMI233Dual: Instrument, ECP eddy current and SMP-2 magnetic induction probes, protective case and set of calibration shims.

 

The CMI 233 is also available with statistical software as optional.

How To Choose An Ultrasonic Thickness Gauge -Part II
 The decision on whether you need to measure  : 1. Thickness of sheet metal 2. Evaluate the onset of corrosion in metal fabricated structures 3. Thickness of small diameter pipes such as boiler tubes, automotive pipes etc amongst others, will decide which thickness gauge instrument you should purchase to satisfy the application. A thickness gauge is an investment in quality production of components, to test quality of product purchased and finally to ensure a higher lifetime of asset by identifying corrosion. Purchasing a world class quality  instrument such as Dakota ultrasonic thickness gauge ensures that your teams are utilizing product which will provide consistency and repeatability in measurements ensuring that the process of quality assurance or quality testing can be inducted into your organization as a process and not as a daunting task. Many a times questions are asked – give us an ultrasonic thickness gauge instrument which is easy to use ...
How To Choose A Material Thickness Gauge - Part I
Thickness gauges are utilized where a micrometer or vernier caliper cannot be utilized – for measuring thickness of large sheets of metal or other substrates which can otherwise not be measured using the above devices. [caption id="attachment_54" align="alignleft" width="150"] Ultrasonic Material Thickness Gauge[/caption] A thickness gauge works on the principle of ultrasonics, i.e a signal is sent into the substrate through the transmitter  of an ultrasonic transducer which when received allows the thickness of the substrate to be measured. While all this sounds so simple, should all ultrasonic thickness gauges not be the same?  Which leads to the questions – 1.  what is the type of substrate under test ? egg, steel, aluminum, iron, titanium, glass etc. 2.  What are the conditions in which the thickness gauge will be used, will there be dust, oil, water ? 3.  Is it a simple sheet of material or a final product ? 4. How thin or ...
