Light (LUX) & Ultra Violet (UV) monitoring using light meters

The ML4000LUX/UV series of light meters enable users to measure light (LUX) and ultraviolet (UV) using the most accurate sensors available. The ML4000 series of light and UV light meters are a range of advanced technology allowing monitoring of a site, with historical analysis of data.
Measurements can be taken of the proportion of UV present (μW/Lumen), the total amount of UV (mW/ M2), and the amount of visible light LUX).

Alternatively, view our Radio Transmitter variants, here.

LUX is measured in the range 10 to 5000 LUX. This is sufficient for environments where a LUX level of over 600 is not normally desired, but higher ranges can be supplied upon request. The UV range is 20 to 2000 μW/Lumen. Typically these data loggers are used for museum UV or light monitoring.
