About Our Company

over 40 years activity

Welcome to METRASTAT

We make it possible for you to take a closer look at the color and appearance of industrial products.

How much closer?
A lot closer, because our proprietary digital Color Image Coding (CIC) technique enables you not only to measure the color of a flat sample in all possible color spaces but also to quantify its

  • chromaticity
  • fluorescence intensity
  • structural homogeneity
  • of course heat stability and light stability
  • … and much more by using our new and revolutionary System for Computer-Assisted Image Analysis


Automatic Testing Ovens and Scanning Reflectometer for Measuring the Short Term Heat Stability and Long Term Heat Ageing of Polymers such as PVC, PVDF, ABS, PA, PE, PP, etc.

Problems with your polymer during processing?

Melting of bad formulas and production stops?

The competition seems far ahead and you want to optimize your formulae?

You need quality control experts who will give you the peace of mind you need.

The METRASTAT SA team of chemists and engineers has developed a brand new system of HEAT STABILTY measurement. It will enable you to test your PVC, PP, PE, etc. with the METRASTAT PLC TOUCH oven and a FLUOSCAN REFLECTOMETER, the analytical system that will give you exact scientific information about: the use of stabilizers and the reaction of your products when exposed to heat (during and after production).

Our team at our new facilities in Switzerland have been working hard to elaborate a system that will enable you to make the best product at the lowest possible cost and without waste of time, energy… and raw materials!


The History

The METRASTAT company is based in the technopôle of Sierre, a technical and communication center well known in the French speaking part of Switzerland for hosting IT companies, the local tech university and the labs for Novelis.

Here our team of chemists and engineers has recently redeveloped the latest METRASTAT HEAT STABILTY TESTING SYSTEM. The new METRASTAT PLC TOUCH OVEN with the newest Siemens automation control modules as well as the FLUOSCAN REFLECTOMETER equipped with white light and UV spectrophotometers from ColotLite compose the system.

We enable you to test PVC, PP, PE and PVDF for quality control AND research and development. It will give you exact scientific information about the use of stabilizers and the reaction of your products when exposed to heat, during and after production.

The company is a family business founded in Paris in 1977 then transferred to Düsseldorf, Germany in 1987 were it had the name PSD Prüfgeräte and then Dr. Stapfer GmbH.

Dr. Christian Stapfer and Mrs. Barbara Stapfer-Koblitz, the two owners, founders and administrators of METRASTAT, managed the company during more than 30 years. Their daughter, Ms. Cassandre Stapfer, was trained in the company for several years before becoming the new Owner/President and Directing Manager of the company since 2008.

METRASTAT SA manufactures and sells to more than 400 customers in 45 countries worldwide. Moreover, it is the long-term expertise and enlightened advice of its inventor, Dr. Stapfer, as well as the reliability and constant research to improve the instrument that makes our reputation.
