DT-1309/ Wide Range Professional Light Meter with USB PC Interface
|
|
|
|
The
DT-1309 Digital Light meter is a precision instrument that is used to measure
illuminance (Lux/ Ft-cd).
|
|
It
meets the CIE photopic spectral response and it is fully cosine corrected for
the angular incidence of light.
|
|
The
illuminance meter is compact, tough and easy to handle and use. The light
sensitive component used
|
|
in
the meter is a very stable, and incorporates a long-life silicon photo diode
and spectral response filter for
|
|
best
accuracy.
