UV Analyzer
The UV Analyzer is an app-based UV measurement device. It consists of the UV Analyzer app for Android and iOS, the UV Analyzer self-adhesive strips and the UV Analyzer stick.
The app can be downloaded via the App Store from App Store® from Apple® or via Google Play free of charge. The UV Analyzer measuring strips and stick are distributed by IST. Please contact Frank Krauß for order processing.
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. The measurements can be exported for quality assurance and documentation.

Recommended measuring range for dose from approx. 200 - 2500 mJ/cm². For further information see FAQs
What factors are important for UV measuring?
There are quite a lot of factors influencing the measuring. Most important are electrical power, distance to UV unit, light spectrum, machine speed and shape resp. color of underground (curved – flat, dark - light).
Recommendation: Respect the warming up time of minimum 5 minutes for the whole unit before measuring and ensure consistent measuring conditions
How to operate the UV Analyzer stick?
Position the stick on the strip, ensure no overlapping and and start measuring in the app. The app allows up to 5 measurements (after repositioning) for each strip. After completion of the desired number of measurements a mean value is automatically calculated. We do recommend minimum 2 measurements.
What is the recommended dose range?
We do specify the UV dose as a rough rule between 125 mJ/cm² and 2500 mJ/cm². In detail the real sector is a function of strip sensitivity and the emmission sectrum of light source. The app will use recommendations depending on the selected type of UV. The UV dose is inversely proportional to machine speed. Means double the speed, half the dose. Therefore a lot of applications are brought up for UV measuring. The app can calculate a dose for a target speed.
What is the meaning of dose@target speed calculation?
It might be that requested dose values exceed the recommended limits of the strips. In this case you should set your machine speed to realize dose values which will be within the limits. The machine speed might now be wrong for your application, but you are able to calculate the exact dose for your desired machine speed with this feature.
What stands the calibration curve for?
The UV Analyzer app is using calibration curves to realize best accuracy. In reference to the type of UV unit and lamp spectrum resp. LED spectrum you have to choose the designated calibration curve. Choosing a calibration curve will get you as well a detailed information for recommended dose levels.
Available calibration curves:
- BLK Hg - (mercury lamps for IST BLK units)
- BLK Fe - (iron doped lamps for IST BLK units)
- LUV3 385 nm - (385 nm LEDs with optics for IST LUV3 units)
- SC 395 nm - (395 nm LEDs without optics for IST/ITL units)
- Generic LED 375-405 nm - (LEDs for all non IST units)
- Generic Hg - (mercury lamps for all non IST units)
What is the UV Analyzer expected to display?
The app shows dose measurements in reference to the type of UV unit and the spectrum, which will work for UV and LED. Before measuring, you can enter and save additional parameters, such as unit number, operating hours, machine name and measuring speed, distance to substrate and power setting. These parameters are informative and have no influence on the actual UV measurement.
What is the advantage of the UV Analyzer?
The UV Analyzer respects that UV strips do not have uniform sensitivity over the complete UV range. The calibration curves with reference to unit type and spectrum take this aspect into account and enable precise measured value assignment. In addition, each stick is referenced to a calibration standard. Through these measures, a high measurement quality is achieved.
How is documentation realized?
The UV Analyzer app offers the possibility to share measurements. A complete protocol can be stored as a pdf-file, transmitted to a printer or an e-mail address. Please note that only the last 10 measurements will be stored within the app. If you try to store more than 10 measurements the oldest measurement is overwritten.
Can I measure non-IST UV equipment with the UV Analyzer?
Of course, that is possible. In this case you have to choose a spectrum (calibration curve) which is close to your usage.
However, the UV Analyzer was developed for IST equipment and calibrated accordingly. This means that you only get the full accuracy in regards of dose measurements with the calibration curves for IST UV units.
