Elsec 7650 / 7650C UV and Light Meter

Elsec 7650 / 7650C UV and Light Meter

Two parameters that cause damage to buildings and precious artifacts are ultra-violet light 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.

Features

  • Measurements: Ultra violet (UV) light, visible light (lux or foot-candles)
  • Data logging (7650C)
  • Output: digital display; USB interface for data download to PC (7650C only)

Benefits

  • 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

Ultraviolet (UV)

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).

Visible Light

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.

Data Logging

The optional data-logging function (7650C) enables over 70,000 readings of both parameters to be automatically taken at selectable intervals (every 10 seconds to 1 hour). The saved data can then be transferred to a computer by a standard USB interface. When logging data the 765 can be turned off to save power and the built in clock will turn the unit on whenever a reading needs to be taken, this enables a 7650C to be left taking readings for months at a time. Software is provided to display the measurements and save the logged data in CSV format that can be accessed and displayed by many programs (e.g. Microsoft Excel).
