The Senseca HD2102.2 Photo-Radiometer Datalogger (developed within the internationally recognized Delta Ohm optical instrument range, part of the GHM Group Italy) is a high-precision, multi-purpose handheld measuring system designed for professional photometric and radiometric monitoring. It serves as an essential measurement workstation for environmental auditors, occupational hygiene inspectors, quality assurance laboratories, photochemical manufacturing plants, and horticultural research centers requiring rigorous assessment of light intensity, luminance, and spectral radiation.

1. MULTI-SPECTRAL RADIOMETRIC & PHOTOMETRIC VERSATILITY VIA SICRAM PROBES
The HD2102.2 instrument interfaces seamlessly with Delta Ohm's smart SICRAM interchangeable probe family (probes embedded with internal memory chips containing factory calibration data and automatic sensor recognition):
• Illuminance (Lux / Foot-candle): For workplace, architectural, and industrial illumination compliance audits.
• Luminance (cd/m² or foot-lambert): Designed for road lighting verification, display screen testing, and illuminated signage inspection.
• Ultraviolet Radiation (UVA, UVB, UVC): Measures spectral bands UVA (315 - 400 nm), UVB (280 - 315 nm), and germicidal UVC (200 - 280 nm) in W/m² or µW/cm² for sterilization validation and UV resin curing control.
• Photosynthetically Active Radiation (PAR): Quantum measurement in µmol/(m²·s) or photon flux, dedicated to greenhouse management and agricultural botany.
• Total Solar Irradiance and VIS-NIR spectral irradiance monitoring.

2. ADVANCED INTEGRAL ENERGY DOSE Q(t) & STATISTICAL FUNCTIONS
• Time-Integrated Dose Calculation Q(t): Automatically computes the time integral of the measured photometric/radiometric quantity [Q(t) = ∫ E·dt]. It quantifies the cumulative radiant energy or light exposure over time (Lux·s or J/m²), an indispensable metric for industrial UV curing lines, photobiological exposure safety, and microbiological disinfection testing.
• Live Statistical Processing: Computes and displays Maximum (MAX), Minimum (MIN), and Average (AVG) statistical metrics throughout any ongoing measurement session.

3. EXPANSIVE DATA LOGGING CAPACITY & REAL-TIME USB TRANSMISSION
• Heavy-Duty Memory Storage: Built-in datalogger capable of recording up to 38,000 samples when using single-parameter probes, or up to 14,000 samples with multi-parameter combined probes.
• Configurable Logging Intervals: Selectable sampling intervals ranging from 1 second to 1 hour.
• Real-time PC Streaming: Equipped with an isolated USB interface enabling live data acquisition onto a PC or batch downloading of stored data campaigns via the dedicated DeltaLog9 PC software suite.
