Reliable illuminance measurements with the LXP-2 light meter

Model for people making basic lighting measurements of indoor and outdoor workplaces. The device works with LP-1 measuring probe (class B) which allows to proceed with measurements in a reliable way. The nonintegrated probe eliminates the influence of the user to the measurement result.

Main features

  • high resolution up to 0.1 lx
  • highly accurate measurements
  • measurements of all types of light sources including:
    • LEDs lamps,
    • incandescent lamps,
    • fluorescent lamps,
    • electrodeless lamps,
    • high and low-pressure lamps
  • no need to using correction factors
  • photodiodes with filters make the spectral sensitivity characteristics well matched to the requirements of C.I.E.

Product functions

  • data-hold for freezing measuring values
  • automatic zeroing
  • peak-hold for freezing the peak signal of light pulse
  • capable of selecting measuring mode in Lux or FC scale
  • MAX and MIN results save
  • relative mode
  • easy to read large backlit display
  • USB connection with PC
  • built-in memory: 99 points
  • 16 000 values records data logger
  • auto power off
