    Radiance Meter

    Overview Knowledge Standards Terms
    A radiometer receives the radiant energy emitted from the target surface through a photoelectric sensor, converts it into an electrical signal, and calculates the radiant flux per unit solid angle. It is used to measure the luminous intensity of material surfaces at specific wavelengths and is applied in the printing industry to detect the brightness of fluorescent inks, evaluate the aging of plastic products, and test the whiteness of paper.
    Selection
    When selecting, pay attention to whether the measurement wavelength range covers the application requirements, and consider the temperature range and surface characteristics of the target. Ensure that the instrument's field of view matches the size of the object to be measured, and that the calibration method complies with industry standards. In terms of environmental adaptability, it should meet the on-site temperature and humidity conditions, and the operation interface should be simple and easy to read.

    Application of Xenon Lamp Aging Test Chamber in Automotive Coatings ASTM G155
    Xenon lamp aging test chambers simulate environmental conditions such as solar radiation, temperature, and humidity to evaluate the weather resistance of automotive coatings under the ASTM G155 standard.
    UV aging test chambers are used for the aging evaluation of polymer materials.
    The UV aging test chamber accelerates the aging process of polymer materials by simulating ultraviolet radiation from sunlight, combined with temperature and humidity control, to evaluate their durability.
    What are the differences between a vacuum oven and a conventional oven?
    The main difference between a vacuum oven and a conventional oven lies in their working pressure. Conventional ovens operate at atmospheric pressure, heating through air convection, making them suitable for routine drying tasks. In contrast, vacuum ovens are evacuated to low pressure to reduce air presence, primarily relying on thermal radiation for heat transfer. This makes them ideal for processing heat-sensitive, oxidation-prone materials or those requiring thorough drying.
