Fischer benchtop units exceed the capabilities of handheld gages by offering more and different measurement techniques. With COULOSCOPE® CMS2 and COULOSCOPE® CMS2 STEP, literally any metallic layer, even multi-layers, can be measured on any substrate. The FISCHERSCOPE® MMS® PC2 can employ up to 8 different electro-magnetic measurement techniques at the same time, resulting in a range 60 different probes.
All Fischer benchtop units offer easy and convenient programming and operating. Extensive evaluation and statistics functions and data export formats are provided. Read the individual product pages to learn more about our benchtop units for coating thickness measurement and material analysis.
Coulometric coating thickness measurement for quality control
Above a certain layer thickness, the non-destructive measurement of layer thickness with X-ray fluorescence reaches its limits. This is where the COULOSCOPE® CMS2 comes into play. It measures the coating thickness of almost any metal layer by using the coulometric method. This is done quite simply by deplating the coating. Many common single- and multilayer coatings can be measured accurately with the COULOSCOPE CMS2.
The coulometric method is a cost-effective, precise alternative to the X-ray fluorescence method – provided you can accept a destructive method for coating thickness measurement. It offers you maximum flexibility, as it can be used for a wide range of coating-carrier combinations. You benefit from the coulometric method of coating thickness measurement especially in the quality control of electroplated coatings, as well as for monitoring the residual tin thickness on printed circuit boards.
STEP TEST: COULOMETRIC COATING THICKNESS MEASUREMENT AND MEASUREMENT OF ELECTROCHEMICAL POTENTIALS
If you want to measure electrochemical potentials in addition to the coating thickness when using the coulometric method, the COULOSCOPE CMS2 STEP is your instrument. The STEP test method allows you to measure the differences in potential and the layer thicknesses of multiple nickel coatings simultaneously – ideal for determining e.g. the corrosion behavior of these coatings.

All-in-one system to measure coatings and test materials
Experience the flexibility of Fischer’s modular measurement system, the benchtop FISCHERSCOPE® MMS® PC2, for both coating thickness measurement and material testing. The instrument can be completely customized to your specific measurement and testing needs via 8 plug-in modules. The interchangeable probes feature the accuracy and repeatability of Fischer’s most popular gages. This all-in-one measurement system saves you time and money by eliminating the need for multiple specialized devices while making your quality management processes more efficient.
An investment in the all-in-one MMS PC2 measurement system pays for itself by reducing the time needed to measure and test your products and increasing your flexibility. For example, when used with the PERMASCOPE® and the SIGMASCOPE® plug-in cards plus their respective probes, you can measure both coating thickness and electrical conductivity with the same instrument. The interchangeable card modules allow the user to perform amplitude and phase-sensitive eddy current, magnetic induction test methods without ever needing to change instruments.
The MMS PC 2 comes with the Windows CE operating system already installed, which turns the benchtop tool into a powerful all-in-one system for measuring, testing, recording and processing. With the touch of a button, your data is easily analyzed, stored and exported – saving even more time in your quality assurance process. The flexibility, accuracy and data handling of the MMS PC2 makes it the ultimate solution for your unique coating measurement and material testing needs.
