Lux1308 Light meter is a precision instrument used to measure illuminance (lux, footcandle) in the field. It is meet CIE photopic spectral response. It is fully cosine corrected for the angular incidence of light. The light sensitive component used in the meter is a very stable, long-life silicon photo diode and spectral response filter. It is ideal for environmental, health and safety checks and industrial applications.

FEATURES

• Easy to read large backlit display
• Light-measuring levels ranging form 0.01lux-0.1klux/0.01fc-0.01kfc, repeatedly
• High accuracy and rapid response
• Data Hold function for holding measuring values
• Unit and sign display for easy reading
• Maximum and minimum measurements
• Relative reading & Reset function
• Automatic zeroing
• Meter corrected for spectral relative efficiency
• Correction factor need not be manually calculated for non-standard light sources
• Short rise and fall times
• Peak Hold function for tracing the peak signal of light pulse with least duration 10μs and keep it
• Capable of selecting measuring mode in Lux or Fc scale alternatively
• Auto power off 30 minutes
