Gigahertz-Optik ensures UVC lamps provide effective and safe disinfection against coronavirus

UVC lamps installed in the upper part of rooms provide effective inactivation of airborne pathogens such as SARS-CoV-2.  They can make an important contribution towards ensuring normal life in shops, offices, schools and hospitals even in these times of coronavirus.

Watch the ZDF Video to see how Europe’s first supermarket irradiated their store with UV-C light to kill coronaviruses.

However, it is important to ensure installations are safe for all occupants whilst providing a sufficient, but contained, dose of UVC in the upper room area.

With its X1-1-UV-3725 UVC radiometer Gigahertz-Optik supplies the perfect hand-held measuring device to obtain high-precision measurements of low-pressure mercury lamp-based installations. It enables testing in accordance with international safety standards as well as ensuring an effective germicidal dose is achieved.

For UVC LED based systems the model X1-1-UV-3726 is recommended as it additionally incorporates calibration factors at LED centre wavelengths 260nm-290nm. For far-UV germicidal sources such as excimer lamps (222nm), model X1-1-UV-3727 should be selected.   It measures irradiance in the range from 200 to 300 nm and is calibrated for use with excimer lamps (222nm), UVC LEDs and low-pressure mercury lamps (254nm).

The detectors of the UV-37xx series were specially developed for radiometric measurements in the ultraviolet spectral range and have proven themselves in industrial and scientific use for many years. They are pre-aged with UV radiation for long-term stability, provide a strictly linear response, reject ambient light and incorporate a precision cosine response diffuser.

Each UVC radiometer is calibrated in our own DIN EN ISO / IEC 17025: 2018 accredited laboratory (DAkkS-certified).

The safe and effective use of germicidal UVC light sources can be guaranteed using the Gigahertz-Optik range of UVC radiometers.
