Light meter "TKA-LUX" (with verification)
Light meter "TKA-LUX" (with verification) The device is designed to measure illumination in the visible region of the spectrum 380...760 nm, created by artificial or natural sources located arbitrarily relative to the receiver. The best domestic lux meter in terms of its characteristics, which is not inferior to world analogues, is reliable and easy to use. Applications: Sanitary and technical supervision in industrial enterprises and organizations (occupational health and safety services, chief power engineer services), educational institutions, research centers, museums, libraries and archives, transport and communications enterprises, metrology and certification centers, medical institutions, State Sanitary and Epidemiological Supervision centers, workplace certification, agriculture and many others. The device is recommended for measuring horizontal illumination from artificial lighting of highways. The device is also suitable for measuring illumination when working with photoluminescent materials (including with photoluminescent materials, for obtaining a license from the Ministry of Emergency Situations. Requirements for illumination measuring instruments are specified in GOST 34428-2018). Manba: https://www.nv-lab.ru/catalog_info.php?ID=8771
