Light, UV, Temperature and Humidity Meter
The Universal Light Meter (ULM) is a hand-held instrument designed to measure LUX and UV and display the readings in an easily understood format. Temperature and humidity measurement is available as an optional extra.
The ULM has internal auto-scaling across the ranges 10 to 20,000 LUX and 10 to 1,000 μW/Lumen. In the normal mode of operation it displays light levels on its alpha-numeric LCD screen as LUX , μW /Lumen and mW/m2. LUX is detected by a photo-metric diode and UV by a silicon carbide sensor which provides a response over the range 250 to 400nm. The sensors are mounted adjacent to each other, with cosine-correction of both LUX and UV.
- LUX is detected by a photo-metric diode

- On-screen menu
- Temperature and humidity measurement is available as an optional extra
- Assists with damage prevention
- Ideal for spot checks or cross checking light and UV conditions
- Provides users with the tools to assist in building maintenance and conservation
