LT300: Light Meter with Digital and Analog display of light in Foot-candles or Lux

Measures light intensity up to 40,000 Foot-candles or 400,000 Lux with high resolution to 0.01 Fc/Lux. Ideal for indoor lighting tests and for checking security and safety illumination in parking garages, night time ATM areas, stairwells, landings, and hallways.

Includes:

  • 9V battery
  • Light sensor with protective cover
  • Protective holster
  • Soft case

Features:

  • Wide range to 40,000Fc or 400,000 Lux with max resolution to 0.01 Fc/Lux
  • Relative mode indicates change in light levels, peak mode captures highest reading
  • Remote light sensor on 12" (30.5cm) coiled cable — expandable to 24" (61cm)
  • Utilizes precision photo diode and color correction filter
  • Large LCD display with analog bargraph
  • Backlight for readings in low light levels
