Checking the quality of UV aggregates flexibly

With the UV-Analyzer, an app-based measuring device, users can independently check the quality of their UV aggregates at any time. The app can be downloaded free of charge. The starter kit includes the UV-Analyzer stick with reference white, charging cable, lanyard and measuring strips and is distributed by UV specialist and manufacturer IST Metz. The UV Analyzer is suitable for any application where UV dose is of interest and is not accessible with conventional meters. The app displays dose measurements in terms of UV unit type and spectrum, which works for both UV and LED. UV Analyzer also takes into account that UV measurement strips do not have uniform sensitivity across the entire UV range. The reference curves referenced to aggregate type and spectrum incorporate this aspect and allow for accurate measurement mapping. In addition, each stick is referenced to a standard. These measures ensure high measurement quality. The measurement is simple: just stick the measuring strip on the substrate and irradiate it with UV light. Depending on the irradiation dose, the measuring strip turns dark blue. The stick is then paired with the app via Bluetooth and the sample is measured within 15 minutes. To do this, users select the appropriate unit in the app and can enter additional measurement parameters, such as unit number, operating hours, speed and distance to the substrate. The app displays the measured UV dose in mJ/cm². This dose value can be compared with the reference value. Reference values for the UV analyzer are determined directly by the user on site when new. The measured values can then be exported from the app for quality assurance and documentation.
