UV Measuring instruments

Every company that owns ovens and UV equipment should be equipped with an instrument to measure the Ultraviolet light. This allows to be always certain that the UV light source is working properly and that the amount of UV radiation is sufficient to the polymerization or to the treatment carried out on the material.

Every company that owns ovens and UV equipment should be equipped with an instrument to measure the Ultraviolet light. This allows to be always certain that the UV light source is working properly and that the amount of UV radiation is sufficient to the polymerization or to the treatment carried out on the material.

Two are generally the values ​​that need to be measured :

  • The UV light intensity (measured in mW/cm2)
  • The total amount of UV radiation during the exposure (measured in mJoule/cm2 )

In some processes , it is also crucial to know the temperature reached from the material during exposure.

The first value is detected by means of an instrument called a UV Meter ( or UV radiometer )
The second value is detected by means of an instrument called a UV Integrator ( or UV dosimeter )
There are also the most complete instruments, which simultaneously measure both values ​​( mW/cm2 – mJ/cm2 ) and also the temperature ( ° C ) .

The sensor ( or probe) that detects the Ultraviolet Light , is equipped with a filter that selects the desired UV band ( total UV , UVC , UVB, UVA , UV- Visible , UV LED ) . Being the measurement carried out within a specific UV band , purchasing the instrument device, must be determined the UV filter according to the processing cycle .

Tools more complex (and expensive ) are equipped with multiple filters or probes in order to perform simultaneous measurements on multiple UV bands ( 2-3-4 channels ) and temperature .
