Relative spectral response
The HD2302.0 is a portable instrument with a large LCD display. It measures illuminance,
luminance, PAR and irradiance (across VIS-NIR, UVA, UVB and UVC spectral regions or
measurement of irradiance effective according to the UV action curve). The probes are equipped
with the SICRAM automatic detection module: in addition to detection, the unit of measurement
selection is also automatic. The factory calibration data are already memorized inside the
instruments. The Max, Min and Avg function calculate the maximum, minimum or average
values. Other functions include: the relative measurement REL, the HOLD function, and the
automatic turning off that can also be excluded. The instruments have IP67 protection degree.
