Radiometers

Senseca radiometers, luxmeters and photo-radiometers, formerly Delta Ohm, are professional instruments designed for measuring light and optical radiation in laboratory applications, industrial control, workplace safety, research and technical verification of light sources. The range includes portable instruments, dataloggers, multi-sensor photo-radiometers and spectro-radiometers for measurements of illuminance, luminance, PAR, UV irradiance, blue light, infrared radiation and spectral analysis in the visible and ultraviolet ranges.

The HD2302.0 and HD2102 series instruments are intended for photometric and radiometric measurements using interchangeable LP471 probes equipped with SICRAM module. Automatic probe recognition allows the instrument to select the correct unit of measurement and use the calibration data stored directly inside the probe, simplifying the transition between measurements in lux, cd/m², W/m², µW/cm², µmol/(m²·s) and other quantities related to the connected sensor type.

For quick field checks, the portable luxmeter is the simplest solution when immediate readings of illuminance, luminance, PAR or irradiance are required. When exposure over time must also be evaluated, models with Q(t) integral calculation allow thresholds to be associated with integrated measurement or integration time. For more structured measurement campaigns, the datalogger version enables internal data storage and subsequent transfer to a PC through dedicated interfaces.

The category also includes specific instruments for evaluating non-coherent artificial optical radiation. The multi-sensor photo-radiometer integrates dedicated sensors for the main spectral bands required for the analysis of UV, UVA, blue light, infrared radiation and illuminance, in accordance with European Directive 2006/25/EC and Italian Legislative Decree D.Lgs. 81/2008. This solution is particularly suitable for prevention and protection activities in workplaces where exposure to potentially critical light sources must be assessed.

For more advanced analysis of light sources, the spectro-radiometer datalogger allows spectral distribution measurements of light in the visible and ultraviolet ranges. Using the visible-range sensor it is possible to evaluate illuminance, correlated colour temperature CCT, chromaticity coordinates, CRI colour rendering index and PAR; with the UV sensor, UVA, UVB and UVC irradiance can be calculated. It is therefore suitable whenever knowing a single value is not enough and it is necessary to understand the quality of light and the spectral composition of the source.

Instrument selection always depends on the type of control to be carried out. For spot checks of illuminance or irradiance, a portable luxmeter with dedicated probe may be sufficient. For tests involving data recording, a datalogger version is generally preferable. For artificial optical radiation assessments, a multi-sensor photo-radiometer is recommended, while for complete light quality and spectral analysis a spectro-radiometer is the appropriate solution.

S.A.M.A. Italia supplies Senseca radiometers, luxmeters, photo-radiometers and spectro-radiometers (formerly Delta Ohm), complete with ACCREDIA calibration carried out directly in Senseca laboratories when required for the selected configuration, ensuring reliable measurements, metrological traceability and compliance with applicable international standards.
