Technical data and functions

Probe for measuring illuminance

  • This measures the V lambda radiation (visible light, equivalent to sensitivity of the human eye).
  • For evaluating lighting conditions, e.g. in the workplace
  • The sensor complies with device class B as per DIN 5032.

Probe for UVA radiation

  • This measures long-wave UV radiation (bronzing effect on human skin).
  • Its spectral sensitivity is weighted towards global solar radiation.

Probe for UVB radiation

  • This measures short-wave UVB radiation.
  • Its spectral sensitivity is weighted towards global solar radiation likely to cause erythema (sunburn) as per CIE recommendation (Commission Internationale de l‘Eclairage). The UV index can be calculated.

Probe for UVC radiation

  • This measures UVC radiation, e.g. Hg line at 256 nm.
  • This probe can be used inter alia in water disinfection units.

Probe for global radiation

  • This measures the solar spectrum in the visible range and in the short-wave IR range.
  • Global radiation comprises both direct and diffused solar radiation.

Probe for infra-red radiation

  • This measures the solar spectrum in the short-wave IR range (excluding the visible range).
  • Global radiation comprises both direct and diffused solar radiation.

Probe for quantum radiation

  • This measures the visible light absorbed by the chlorophyll in plants during photosynthesis.
  • It determines the level of quantum radiation in the spectral range specified.
  • It is used to assess the conditions in which plants develop in open field and greenhouse cultivation.
