UV Radiometers

Our VLX-3W radiometer offers precise and immediate measurements of UV radiation at 254, 312, or 365 nm. Its silicon photoelectric sensor records the UV intensity directly, without needing to convert it into visible light. This technology ensures accuracy across the full measuring range from 0.1 to 250 mW/cm². You can track either instantaneous intensity in mW/cm² or accumulated energy in J/cm², depending on your needs. Each sensor is wavelength-specific and interchangeable, so you attach only the one required for your measurement. They also include interference filters that isolate the selected UV band and block unwanted radiation. A quartz disk protects the sensor for long-term use, and the absence of internal electronics prevents temperature effects for stable performance. Results appear instantly on the large microprocessor-controlled LCD screen, making this radiometer both practical and reliable.
