    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
