Best radiation pyrometer is designed and manufactured according to the functional relationship between the radiant energy of the object in the entire wavelength range and its temperature. It uses a radiation temperature sensor as a primary instrument and an electronic potentiometer as a secondary instrument. It is a lens-focused temperature sensor. The device has an aluminum alloy shell, the front is an objective lens, and a thermopile compensation diaphragm is installed in the shell. There is a baffle plate on the field of view diaphragm close to the thermopile. The function of the baffle plate is to adjust the radiation to the thermopile. The radiation energy of the product has a uniform graduation value. Eyepieces are installed on the detachable back cover to observe the image of the measured object.

The Best radiation pyrometer does not touch the object to be measured during the measurement, and the environmental factors at the installation site will have a great impact on the measurement. The interference of external light means that the external light source is incident on the surface to be measured and is reflected and mixed into the measurement light. Such as sunlight during outdoor measurement, illuminating light during indoor measurement, nearby heating furnaces and flames, etc. Set a shielding device for some fixed and unavoidable external light sources. If it is working in a high ambient temperature, the shielding device will synthesize a new heat source. It needs water or air to cool it to reduce its radiation and change the measurement. Direction, avoiding external light.

The spatial distance between the measured surface and the Best radiation pyrometer is called the optical path. In the air at the production site, there are water vapor, carbon dioxide, floating scum, smoke, oil mist, dust, water vapor, and carbon dioxide. The gas medium has selective absorption of radiant energy and has certain wavelengths of radiant energy. It has the ability to absorb, but it is easy to transmit radiant energy of other wavelengths. The absorption of radiant energy by scum, smoke, oil mist and dust is non-selective, but it is accompanied by scattering, which weakens the incidence of the thermometer. The radiant energy caused by the measurement error, clean compressed air can be used to clean the light path to blow away the smoke, and the salt bath furnace is often deoxygenated to remove the slag to maintain the normal brightness of the salt surface.
