Dimensions

– signal processing unit (no more) 130 x 70 x 30 mm
– photometric head with a probe (no more) 230 x 48 x 55 mm
Device weight (no more) 0,4 kg
Battery – Krona battery standard size 9 in

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

Substantial benefits

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.
