UV Light Meter (UV & Lux)

UV light meters can help protect works of art, by monitoring the levels of exposure. It is recognised that a major cause of damage to museum works of art can be light, with the most damaging being the UV content.

These light meters measure proportion of UV present (µW/Lumen), the total amount of UV (µW/M²) and the amount of visible light present (Lux). The amount of UV should be as little as possible and in general should not exceed 20µW/M² or 75µW/Lumen. Normal museum light levels should be limited to 150-250 Lux. Once measurements have been observed action can be taken, light levels altered, if necessary UV filters fitted to display cases, windows and fluorescent tubes.

The UV light meter (952-7650) will measure UV present (µM/Lumen) the amount of UV (µM/M²) and the amount of visible light present (Lux or Foot-candles).

For data logging you will require product 952-7650C. The 7650C (with logging) is the same as 7650 with data logging capacity for over 70,000 readings of all parameters. No special software is required, logged information is stored on an internal USB Flash disc and the data can be downloaded onto a PC and viewed with any spreadsheet (Excel etc).
