RTI Light Probe


Measures the brightness on monitors with the same spectral response as the human eye.

The RTI Light Probe is designed to comply with the needs of QA in modern X-ray departments.

With a monitor and a lux adapter, the RTI Light Probe measures the brightness on monitors and film viewing boxes and the ambient light in the room. It has the same spectral response as the human eye! This makes it reliable for all different types of measurements, independent of the light source.

The spectral response complies with the CIE V(λ) curve.

All prices include freight cost. Pricing does not include Applicable Taxes or Customs Fees.
