HD30.1 Spectroradiometer Data Logger

The HD30.1 performs spectral analysis of light across the visible and ultraviolet ranges, and its design aims at maximum flexibility of use.

System layout

Two parts connected by a cable make up the system: the HD30.1 data logger-indicator and the measuring probes, which are also offered together as a kit under code HD30.1K. The spectral range depends on the probe fitted:

• HD30.S1: visible spectral region (380nm-780nm)
• HD30.S2: ultraviolet spectral region (220nm-400nm)

The probes are interchangeable and come calibrated, each one storing its own calibration file.

Photo-colorimetric quantities from the HD30.S1

Working over the visible region (380nm-780nm), this probe calculates:

• Illuminance [lux]
• Correlated color temperature CCT [K]
• Trichromatic coordinates [x,y] (CIE 1931) or [u',v']
• CRI (color rendering index, R1...R14, Ra)
• PAR [µmolphot/sm2]

Radiometric quantities from the HD30.S2

Working over the ultraviolet region (220nm-400nm), this probe calculates UVA, UVB and UVC irradiance, all in W/m2.
