Luxmeter measuring correlated colour temperature (CCT) up to 150000 lx CRM 40 PCE Instruments

Product description:

• The luxmeter is used to determine photometric magnitudes in the field of light measurement.
• Ergonomic, with large data display.
  • 3.2" LCD colour display.
• The user can determine:
  • The dominant wavelength within the sensitivity range (between 360 and 780 nm).
  • The colour density (Pe).
  • The correlated colour temperature (CCT) in Kelvin.
• It is an ideal tool for taking white LED colour temperature measurements, as the device measures the chromaticity of the phosphor and inspects the light quality output of the assembled white LED.
• It has a detachable receiver head, which allows it to be used in dark rooms or in inspection system installations.
• It has an LED sorting function.
• It has USB interface, with SD card slot and cable for easy data transfer.
• Delivery includes:
  • Colourimeter PCE-CRM 40.
  • USB power cable.
  • USB cable.
  • Luminous density adapter.
  • USB stick.
  • Belt pouch.
  • Hand strap.
  • Carrying case.
  • Instruction manual.
