Is it illegal for a company to use a pyrometer?

Not illegal. Thermal imaging contains a lot of civilian so-called civil field, refers to the power, construction, medical, petrochemical and thermal imaging and other fields, thermal imaging in line with the civil field, so the company with thermal imaging is not illegal. Internationally, infrared thermal imaging cameras are widely used in these fields. However, the application of infrared thermal imaging camera in these civilian areas in China is still in its infancy, the whole development space is still relatively large. Thermal imaging camera and does not belong to the spy equipment, the army and special forces can also be used.
