TESTING & MEASUREMENT
When a substrate is too thin , standard probes may give misleading readings even after a corrective calibration . In these instances , Helmut Fischer GmbH offers a list of high-frequency probes . Their distinguishing feature is that eddy currents are induced in the skin of relatively thin substrates , to allow reliable coating thickness measurements without influence from the variation of substrate thickness .
Final Instrument Choice
The market is saturated with a broad range of coating thickness gauges , so it may initially seem too overwhelming to choose an instrument from the wide range of options available , especially when it doesn ’ t accurately explain what the right choice is .
In these instances , it may become extremely tempting to go for the cheapest option that the market offers . However , as attractive as it may be , the final decision should always be guided by the coating thickness measurement applications .
At Helmut Fischer GmbH , purchasing a coating thickness gauge isn ’ t just a matter of Googling online and pressing the “ buy now ” button , of course . Providing the customer has the right knowledge to make an informed decision ; it can become that simple .
The link further below leads to gauges , that are offered by Helmut Fischer GmbH – DFT gauges with a built-in probe for straightforward applications and more advanced instruments that can accommodate numerous specialist probes for more challenging measurement tasks .
