The difference in the function of the relative spectral sensitivity of the photodetector of the Luxmeter is corrected by a system of light filters to match the function of the relative spectral luminous efficiency of monochromatic radiation for daytime vision V (λ) according to GOST 8.332.
The effective reference plane of the Luxmeter coincides with the front plane of the cosine attachment of the photodetector
It combines the functions of a universal light meter, a UV radiometer with increased sensitivity, and a temperature and humidity meter. Faster response, improved performance, high precision platinum temperature sensor, low power consumption.
“TKA-KHANITEL” is a multifunctional measuring complex for research and operational control of microclimate parameters affecting objects of socio-cultural and artistic-historical significance in museums, archives, warehouses, for use in cultural and art institutions, school and local history clubs.
