Wavelength Matters

So what makes us different? We believe that wavelength matters. Why does wavelength matter? Because thoughtful wavelength selection can dramatically reduce or even eliminate errors due to optical obstructions, emissivity variation, background reflections, and misalignment. With thousands of successful installations all over the world, we have developed a wealth of information on how Williamson Infrared Pyrometers can improve productivity and quality in just about any application.
