UV Datalogger – UVMicrolog
Compact UV Datalogger UVMicroLog for High-Precision Recording of UVA, UVB, and UVC Irradiance and Dose
The UVMicroLog is an ultra-compact, high-precision UV datalogger designed for autonomous recording of ultraviolet irradiance and cumulative dose in both indoor and outdoor environments. Developed with advanced SGLUX SiC or GaP photodiode technology, the UVMicroLog measures UVA, UVB, and UVC radiation with exceptional accuracy, traceable to NIST/PTB standards. Featuring a robust solid-state design, integrated memory, and configurable sampling intervals, it can store thousands of time-stamped measurements without external connections. Data retrieval and configuration are handled via UVLog software, providing graphical display, trend analysis, and report generation. Compact, battery-powered, and IP65-rated, the UVMicroLog is ideal for UV disinfection validation, solar exposure studies, and material ageing tests. Combining traceable calibration, long-term stability, and portability, it’s the preferred choice for scientific, industrial, and environmental UV data logging.
Understanding UV Datalogger - UVMicrolog
The UVMicroLog is a self-contained UV measurement system capable of recording irradiance and exposure dose over long durations without a computer connection. Users configure logging parameters such as interval, duration, and sensitivity via PC software before deployment. Once placed in the measurement environment, the unit automatically logs UV data, storing it in non-volatile memory for later analysis. The compact enclosure protects against dust, moisture, and sunlight, making it suitable for outdoor installations, lab research, and process monitoring. Each device includes a factory calibration certificate ensuring traceable accuracy and reliable UV measurement for professional and research-grade use.
