Reliable illuminance measurements with the LXP-10A light meter

Device of the highest class A thanks to cooperation with LP-10A measuring probe. Therefore it allows to make the most accurate measurements in industrial zones and public facilities. In addition, the instrument has the ability to wirelessly send data to Sonel Reader PC software.

Main features

  • measurements in class A
  • high resolution up to 0.001 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
  • wireless connection
  • built-in memory: 999 points
  • 16 000 values records data logger
  • auto power off

Specification

The most important features:

  • Measurement resolution:  0.001 lx (0.001 fc).
  • High accuracy and fast response.
  • Data-hold function for holding measuring values.
  • Automatic zeroing.
  • No need for correction factors calculating  for different light sources thanks to a very good fit spectral sensitivity guaranteeing the correct measurement of intensity of the illumination regardless of the nature of radiation.
  • Peak-hold function for tracing the peak signal of light pulse with duration longer than 0.1 s and less than 1 s.
  • Capable of selecting measuring mode in Lux or FC scale alternatively.
  • Auto power off (5,10 or 15minutes) or disable AUTO power off.
  • Maximum and minimum measurements.
  • Relative reading.
  • Easy to read large backlit display.
  • USB output connect with PC.
  • Data transmission via radio connection using an optional adapter OR-1.
  • Six measurement ranges.
  • Built-in memory –  999, with can be checked in the meter or PC.
  • 16000 values records data logger (traceable only in PC).
