The ML4000 LUX / UV light meter series of data loggers and radio transmitters (Previously known as the LuxBug range) enable users to measure light (LUX) and ultraviolet (UV). The ML4000 series of light (LUX) and UV data loggers and radio transmitters 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).

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.


*These are a guideline only, users are asked to determine their own Lux recommendations as heritage pieces vary in state depending on their age and condition.
