Fibre Probe UV Radiometer
High-Precision Fibre Probe UV Radiometer for Accurate Measurement of UV Intensity in Industrial and Research Applications
The Fibre Probe UV Radiometer is an advanced ultraviolet measurement system designed for precise, real-time monitoring of UV radiation intensity across a wide range of industrial and laboratory environments. Equipped with a fibre-optic probe, it allows remote measurement at difficult-to-reach or high-temperature locations while maintaining exceptional optical accuracy. The radiometer can measure UV-A, UV-B, and UV-C bands, making it ideal for UV curing, disinfection validation, photolithography, and materials testing applications. Its robust photodiode detector (SiC or GaP based, depending on configuration) ensures excellent spectral selectivity and long-term stability, even under prolonged UV exposure. The system features a high-resolution digital display, analogue and serial output options, and calibration traceable to international UV standards. Compact, durable, and easy to operate, the Fibre Probe UV Radiometer is a reliable instrument for industries and research institutions requiring accurate UV dose and irradiance measurement with minimal setup time.
Understanding Fibre Probe UV Radiometer
The Fibre Probe UV Radiometer combines fibre-optic flexibility with precision UV detection, enabling accurate measurements even in harsh or confined environments. Its fibre probe transmits UV light to a calibrated detector unit that quantifies irradiance (mW/cm²) or total UV dose (mJ/cm²). Depending on the model, it can detect narrowband or broadband UV sources in the UVA (315–400 nm), UVB (280–315 nm), or UVC (200–280 nm) regions. The radiometer’s modular design supports interchangeable probes, allowing users to select fibre length and spectral range. With stable electronics, low noise, and robust calibration, it ensures repeatable UV monitoring for industrial, medical, and R&D applications.
