**Disclaimer: The app requires additional equipment and requires adequate use. Incorrect use does not entitle the user to make any claims against IST METZ GmbH & Co. KG.

The UV Analyzer Stick and the UV Analyzer measuring strips are distributed by IST Metz GmbH & Co. KG. Measuring is quite easy. Put the strip on your substrate, irradiate it with UV and measure the strip with the stick. The app will show you the measured dose in mJ/cm². This dose value can be compared with your reference value. Reference values for the UV Analyzer are determined directly by you on site when the system is new.
