PHOTO-RADIOMETER HD2302.0, Merk : DeltaOhm

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 fi tted with the SICRAM automatic detection module: in addition to detection, the unit of measurement selection is also automatic. The factory calibration settings 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 disabled.The instruments have IP67 protection degree.

A particular type of photodiode and a combination of special fi lters bring the spectral response closer to the UV action curve.CEI EN 60335-2-27 standards estabilish a maximum allowable dose of 100J/m2 for fi rst-time exposure and an annual dose of 15000J/m2.The typical spectral response curve of LP 9021 ERY is shown in the Figure together with the UV action curve.The good accordance between the two curves enables the instrument to take reliable measurements of different types of lamps (and fi lters) used at present for tunning machines.Each probe is individually calibrated at DeltaOhm photo-radiometry laboratory by means of a double monochrome. Calibration is performed at 290 nm through a SIT calibrated reference photodiode.
