Compact UV Datalogger UVMiniLog for Precise, Portable Recording of UVA, UVB, and UVC Radiation Levels
The UVMiniLog is a compact and high-accuracy UV datalogger designed for continuous recording of ultraviolet irradiance and exposure dose in field and laboratory environments. Built with a factory-calibrated SiC photodiode sensor (traceable to NIST/PTB standards), the UVMiniLog provides precise measurements across UVA, UVB, and UVC spectral regions. Its integrated memory, low-power microprocessor, and USB interface allow autonomous operation for weeks, storing up to 100,000 time-stamped readings without a PC connection. The included UVLog software enables easy setup, graphical display, and data export for further analysis. Housed in a weather-resistant IP65 aluminium enclosure, the UVMiniLog is ideal for environmental monitoring, UV curing validation, disinfection verification, and outdoor exposure studies. Combining accuracy, portability, and long-term data stability, it delivers reliable UV tracking for scientific, industrial, and environmental applications.
Understanding UV Datalogger - UVMinilog
The UVMiniLog operates as a stand-alone UV measurement and recording device, capable of logging irradiance (mW/cm²) and cumulative dose (mJ/cm²) over defined intervals. Users can configure sampling rates, measurement ranges, and recording duration through UVLog PC software before deployment. After data collection, results can be visualised as time-intensity plots, dose curves, and UV Index trends. The integrated temperature sensor compensates readings for ambient changes, ensuring accuracy in outdoor or laboratory conditions. Compact, battery-powered, and robust, the UVMiniLog offers traceable, repeatable UV monitoring without constant supervision, making it ideal for remote validation and long-term exposure studies.
