Stick-shaped small light sensor (window diameter 9 mm) for narrow position or area

Made in JAPAN

  • Easy-to-carry pocket size.
  • Separate, stick-shaped light sensor (window diameter 9 mm) from the main body enables measurement of a narrow position or area. The light sensor can also be integrated with the main body for measurement.
  • 4039 full-scale count with a bar graph display.
  • Improved measurement accuracy by using a silicon photodiode, which has a spectral sensitivity approximating the relative luminous efficiency specified by CIE (Commission Internationale d'Eclairage), in the light sensor.
  • Wide measuring range of 0.1 lx to 403.9 klx (403,900 lx).
  • Data hold function.
  • Auto power save function prevents wasting of battery power.
