The Elsec 7650 and 7650C enable measurement of two parameters that cause damage to buildings and precious artifacts: ultraviolet light (UV) and visible light.
The Elsec 7650 series light meters combine UV and visible light measurements into a single unit for indoor conservation applications. With the Elsec 7650, anyone can take measurements straight out of the box with little, if any, reference to the instruction manual.
The 7650 measures and displays visible light (Lux or Foot candles), UV light (mW/M² and µW/lumen). Similar to 765 but without humidity and temperature sensors.
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). A free application (RView) is also available for download that displays the data as a zoomable graph that can be saved as an image for inclusion in documents and/or printed.
Provides instant information on visible light (Lux or Foot candles) and UV light (mW/M² and µW/lumen)
Assists in conservation in museums, libraries and art galleries
Measurements: Ultraviolet (UV) light, visible light (lux or foot-candles)
Data logging (7650C)
Output: digital display; USB interface for data download to PC (7650C only)
Using the Elsec 7650 (C), measurements can be taken of the proportion of UV present (µW/lumen) and the total amount of UV (mW/M²).
The amount of visible light is important, not only to check illumination in work areas, galleries etc but also to control damage to light-sensitive objects that is also caused by normal light. Measurements can be displayed as Lux or Foot-candles.
