Lightweight and compact due to optical separation, significantly improved brightness accuracy and measurement range!
The "BM-9A" is a lightweight, compact, and portable handheld luminance meter. As a successor to the long-popular "BM-9," it has significantly improved luminance accuracy and measurement range while keeping the price nearly the same. By selecting and exchanging among three types of light-receiving units with different measurement angles, it can be used for a wide range of applications. Additionally, the light-receiving unit can be separated from the main body, making it suitable for use in system devices and production lines. 【Features】 ■ Handheld, low-cost, multifunctional ■ Three types of light-receiving units can be selected and exchanged, automatically recognized, and measurement results displayed directly ■ Built-in USB for communication with PCs and use in production lines and system devices ■ Keyboard unit allows selection of correction factors and deviation measurements For more details, please contact us or download the catalog.
