ML4000LUX/UV Light Measurement Radio Transmitters

Light Measurement

Light (LUX) & Ultra Violet (UV) monitoring

The ML4000LUX/UV series of radio transmitters enable users to for light measurement (LUX) and ultraviolet (UV) using the most accurate sensors available. The ML4000 series of light and UV radio transmitters are a range of advanced technology allowing 24/7 monitoring of a site, with immediate alarm notification of breach to pre-set boundaries and 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 reliable transmitters are used with our renowned wireless Hanwell EMS monitoring system for real-time 24/7 data (anytime and anywhere) and instant alarm notifications. Contact us today for your free quotation and signal strength test (we can prove ours to be unrivaled) or to discuss your specific temperature monitoring requirements and application.
