Smartphone Based UV Radiation Index Meter – Safester UVI
Smartphone UV Radiation Index Meter Safester UVI for Portable, Accurate UVA + UVB Exposure and Safety Monitoring
The Safester UVI is a compact, smartphone-based UV radiation index meter designed for real-time monitoring of UVA and UVB exposure. It instantly converts any compatible smartphone into a professional UV measurement instrument via a direct plug-in interface and the intuitive Safester App. Equipped with a factory-calibrated SiC UV photodiode, traceable to NIST / PTB standards, the Safester UVI measures irradiance (µW / cm²), dose (mJ / cm²), and a UV Index (0–11 +) according to international standards. It is ideal for environmental safety, dermatological research, outdoor UV monitoring, and educational training. With battery-free operation, fast response, and graphical mobile display, Safester UVI delivers traceable accuracy, portability, and ease of use in one intelligent device. Whether verifying solar UV levels, testing UV filters, or studying exposure risks, the Safester UVI provides reliable UV awareness anytime, anywhere.
Understanding Smartphone Based UV Radiation Index Meter - Safester UVI
The Safester UVI works by detecting UVA and UVB radiation using a precision SiC photodiode calibrated to absolute spectral response standards. Once connected, the Safester App displays UV irradiance, cumulative dose, and a colour-coded UV Index representing potential exposure risk levels. Users can log data, view intensity-versus-time graphs, and generate exposure summaries. Because it draws minimal power from the smartphone interface, no batteries or chargers are required. The Safester UVI helps individuals, researchers, and safety professionals accurately assess sunlight exposure, UV lamp performance, and protective equipment efficiency, making it a practical and educational UV safety companion.
