Magnetic temperature meter revealed

Those who wish to renovate their houses and make them more energy-efficient often use the well-known yellow to blue thermal images to visually identify weak spots applying infra-red measurements. Thermographic imaging is also used in industry for materials testing. Depending on the material, however, the method can result in large measurement errors. Scientists have now developed a technology that visually identifies the slightest temperature differences with high spatial resolution, whatever the material. —> Read More
