Elsec 775 Series - Universal Light Meter
The Elsec 775 series enables measurement of ultra-violet light, visible light, temperature and thermal infrared.
With the Elsec 775, anyone can take measurements straight out of the box with little, if any, reference to the instruction manual.
Using the Elsec 775, 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.
The optional data-logging function (775C) enables over 70,000 readings of all four 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 775C 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 775C 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).
