Broad
Range Lux/FC Meter, 840022
|
All of the
functions of Light Meter 840020, plus max-min-avg
functions, automatic power off, RS232C output and a detachable probe for
easier replacement or repair. Higher range of up to 50,000 lux, 5,000
footcandles. A unique and very useful function is the meter's ability to
compensate for the different colors of tungsten, fluorescent, mercury
and sunlight, with the push of a button. The result is readings true to
actual lighting conditions. Also able to compare the % difference
between two light intensities. A special contrast control allows the LCD
to be clearly read from different angles. Comes with a soft carrying
case and 9V battery.
