In UV curing applications requiring deep curing of adhesives and paints, UV-A radiation for stimulating photoinitiators is the largely standardized spectral range. UV radiometers for these applications must be designed in such a way that they only measure the irradiance in the actinic range of the photoinitiators.


Product description
RCH-111 irradiance detector

The UV detector RCH-111 was specially developed for use in UV radiation curing with discharge lamps. It offers all the features and functions of the detectors of the RCH series (link to RCH-xxx series data sheet). Its spectral responsivity covers the wavelength range from 345 to 385 nm, which is used in particular for the deep curing of adhesives and paints.


Calibration

The detectors are calibrated with regard to their responsivity to irradiance and are supplied with a factory calibration certificate that corresponds to the high standard of the measuring laboratory for optical radiation measurements of Gigahertz-Optik. If necessary, a test certificate accredited according to DIN EN ISO / IEC 17025 can optionally be created for the detector with the associated measuring device.
