INTRODUCTION
One of the primary responsibilities of the custodian of artworks and museum artefacts
is to preserve them for future generations. How they are stored and displayed is
central to this, the 764 Environmental Monitor is an easy to use tool to help in
achieving the safest long term protection.
For many years it has been recognised that one of the major causes of damage to
museum objects and other antiquities is the fading and rotting effect of light on the
object. The most damaging part of the illumination is its ultraviolet (UV) content.
Using the 764 measurements can be taken of the proportion of UV present as
microwatts per lumen (mW/lumen), the total amount of UV as milliwatts per square
meter (mW/M
2
) and the amount of visible light present (Lux).
Most objects are also sensitive to humidity and temperature. The 764 also measures
humidity as % relative humidity and temperature as °C or °F.
The 764 can be left for extended periods to log the above parameters at a user set
interval (10 seconds to 1 hour). The saved data can then be transferred to a computer
for display, graphing etc.
