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.
Features:
Light-measuring levels ranging form 0.1 Lux ~ 0.1 kLux / 0.01 Ft-cd ~ 0.01 kFt-cd
High Accuracy and Fast response
Data-hold function holds measurement value
Auto zero function
Meter corrected for spectral relative efficiency
Built-in Correction factor for non-standard light sources.
Peak-hold capture function for short duration light pulses
Auto power off (20 min.)
Max / Min measurements
Relative reading
Easy to read large backlight display
USB output connects with PC
Auto ranging
