Reference UV Radiometer – UVRRM
Reference UV Radiometer UVRRM for Precision Calibration, Verification, and Traceable Measurement of UV Irradiance and Dose
The UVRRM Reference UV Radiometer is a high-precision instrument designed for traceable calibration, validation, and verification of UV irradiance and exposure dose.
Engineered with NIST/PTB-certified detectors, the UVRRM serves as a primary or secondary reference standard for laboratory and industrial UV measurements. It delivers outstanding accuracy and long-term stability across the UVA, UVB, and UVC spectral regions.
Equipped with a temperature-stabilised photodiode amplifier and digital output interface, the UVRRM provides real-time measurement data for calibration laboratories, UV curing system verification, and radiometer cross-checking.
Its compatibility with SGLUX UVPLOT software enables automated logging, analysis, and certificate generation.
Whether validating production-line radiometers, performing annual instrument recalibration, or conducting research-grade irradiance studies, the UVRRM sets the benchmark for traceable, reproducible, and scientifically certified UV measurement performance.
Understanding Reference UV Radiometer - UVRRM
The UVRRM Reference UV Radiometer functions as a traceable calibration reference used to verify the performance of other UV measurement instruments.
It combines a stabilised photodiode sensor, low-noise amplifier, and digital control electronics to deliver consistent irradiance readings with minimal drift.
When paired with UVPLOT software, it allows real-time graphing, data comparison, and certificate generation.
Each detector is calibrated at SGLUX’s PTB-accredited laboratory and supplied with a calibration certificate detailing responsivity, uncertainty, and spectral range.
The UVRRM ensures that every UV measurement—whether for disinfection, curing, or research—is scientifically reliable and internationally traceable.
