Light

Correct lighting conditions in general is a crucial factor for people's well-being. Good lighting in the workplace, whether artificial or natural light, increases staff's ability to concentrate, promotes their health and reduces their complaints. For the measurement of light conditions, Testo offers lux measuring instruments which can be used to measure the luminous intensity of natural or artificial light. In addition to Testo Light meters, the lux probe of the testo 435 multi-function measuring instrument can also determine the flicker frequency of screens which also has an influence on workplace assessment.
