Lux meters for measuring brightness in lux, fc or cd/m². Some lux meters are equiped with internal memory or a data logger to record the measurments. The measurment of light intensity with these lux meters are, each day, becoming more important in the workplace where protective screens are needed. The technique of measuring enviromental conditions, to which the measurement of light belongs, also occupies a lead position in scale of importance. Lux meters with data loggers as shown inour on-line store, are highly regarded especially due to their cosine correction of the angle of incident light. These lux meters have memory to store measured values, and software to analyse readings. We also offer a meter for measuring UVA radiation.
