L-50

Luxmeter

Is designed to measure the illuminance of natural and artificial radiation of point sources or scattered light.

Class A

 

Precision of measurement

Good spectral matching to the spectral sensitivity V( λ) and directional response to the cosine function guarantee the accuracy of illuminance measurement, regardless of the nature of the radiation. It does not require the use of any adjustment coefficients for different light sources.

Features

  • Lack of necessity for the use of adjustment coefficients for different types of lighting.
  • Automatic switching-off when it is not used.
  • HOLD function used to stop the measurement.
  • Low battery signalling prevents from incorrect readings of measurement result.
