Insulating Materials: Increase Your Efficiency in Quality Assurance!

NETZSCH Has Introduced a New Line of Thermal Conductivity Testers – The HFM 446 Series!


“Time is money!” – We all agree on that. How strange that so many people who work in quality assurance and production control are still struggling with paperwork and tailor-made Excel solutions for documenting quality levels. And why – when it’s so easy to map processes digitally with EPR systems and quality assurance software nowadays?

More often than not – and despite the best of intentions – such systems do not actually extend into all areas of a company in order to make work any easier. Many employees even report that it is more efficient to work with “isolated solutions”.

With the new HFM 446 thermal conductivity tester series, NETZSCH started from scratch in the process of quality assurance. Many functions facilitating your everyday quality assurance work can be found directly in the appertaining software.

It almost goes without saying that the instrument series is available in three different sizes – depending on the application!

Register today and win a 150-day trial of an HFM 446 Medium for your quality assurance! The winners will be informed after IEX 2018. 

In the quality assurance of insulating materials intended for the European market, you are obligated as a manufacturer to carry out your own factory inspection of the thermal conductivity within the framework of the CE declaration of conformity. The representative thermal conductivity value, however, is not the individual value measured on random samples, but the nominal thermal conductivity value declared by the manufacturer on the product label in the end. This value is based on a statistical survey – known as the Lambda 90/90 – of a variety of in-process test results; in effect, it is the thermal conductivity value that a manufacturer can guarantee for 90% of his output with a probability of 90%.

In addition, many products have nominal thicknesses for which the thermal conductivity can only be determined via measurement techniques to a limited extent. Here, it is advisable to cut layers from a thick product that are easy to measure. At the end of the process, however, these must again be assigned to the nominal thermal conductivity value of the thick product.

With the HFM 446 series by NETZSCH, you can calculate the Lambda-90/90 in accordance with standards at the touch of a button from a multitude of measured values – if necessary, also individually for each of the product types that are manufactured in your factory. There is no need to transfer data to other systems – the documentation is generated fully automatically, in parallel with your measurement activities.

Come and see our products live at IEX 2018 – and don't miss the opportunity to win a free trial period.
