UV Analyzer

UV MEASUREMENT DEVICE

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.

Stick measuring strip on a white (light) substrate

 

Irradiate the measuring strip with UV light; the measuring strip turns dark blue

 

Take the measurement with the UV stick and transfer to the app via Bluetooth

 

Performance of the measurement

Remove the measuring strips from the light-protected packaging. Separate individual measuring strips. The measuring strip has a practical peel-off aid.

 

Recommended processing time until irradiation less than 15 min, remove measuring strip and stick on a white (light) substrate.

 

Irradiate the measuring strip with UV light; depending on the irradiation dose, the measuring strip turns dark blue. Each UV lamp should always be measured individually.

 

After irradiation, evaluate the measuring strip within 15 minutes.

 

Call up the app, select a suitable calibration curve depending on the unit and enter the measurement data. The app recognises the measuring strip and saves the photo for evaluation.

 

Place the UV stick on the measuring strip and take the measurement. The measured value is transferred to the app via Bluetooth.

 

A maximum of 10 measurements can be saved. Sharing the measurement data creates a measurement protocol.

 

Technical specification

Store between 0 - 20 degrees, do not expose to direct sunlight and protect from moisture, store measuring strips in the supplied packaging, recommended storage time maximum 6 months

 

Sensitivity of the measuring strips from 200-420 nm. Recommended measuring range for dose from 50 - 2000 mJ/cm², varies depending on aggregate and spectrum

 

FAQ

Any Application where UV dose is of interest and that can’t be accessed via conventional UV dose measuring devices.

 

We do specify the UV dose between 50 mJ/cm² and 2000 mJ/cm². 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 target dose for a defined speed.

 

We do recommend not to overlay a period of 6 month. During this period the strips should be stored under dark and dry conditions.

 

Of course, that is possible. We will be supplying general UV unit measurement possibilities in the future. 

 

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 units. 

 

No, the App will only recognize ISTs UV Analyzer strips, third party strips are not supported. 

 

In every package of the UV Analyzer is a white standard included. This is used for calibration.

 

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.

 

There are quite a lot of factors influencing the measuring. Most important are electrical power, distance to lamp, lamp spectrum, machine speed and shape resp. color of underground (curved – flat, dark - light).

 

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.

 

Position the stick on the strip, ensure no overlapping and press the button measuring. 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.

 

There is a certain sensitivity (up to 420 nm) to ambient light. Therefore we recommend no massive light impact before and after UV radiation. You should also consider a maximum of 15 minutes before and after UV radiation.

 

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 do handle this aspect. This will ensure best measuring quality.
