ILT2400 Germicidal and Optical Hazard Chart

Effective Germicidal Detector

Configured with a spectral response weighted to match the IES Luckiesh and DIN standards for germicidal effectiveness.

Measurement Range: 8e-8 to 1e-3 effective Watts/cm2
Germicidal Spectral Range: 235 – 307 nm, calibration wavelength at 270 nm
Dimensions: 68 mm x 42 mm diameter
Order part number: ILT2400 (meter), SED240/T2ACT5 (Detector)
Applications: This detector has a weighted response and is specifically designed to measure the germicidal effectiveness of low-intensity, broad spectrum UV sources in accordance with the requirements within the IES Luckiesh and DIN standards.


Actinic Optical Radiation Hazard Detector


Specially designed with proprietary filtration for easy and accurate optical radiation hazard measurements in the UV Actinic range.


Measurement Range:  8e-8 to 1e-3 eff W/cm2
Hazard Spectral Range: 180 – 400 nm
Order part number:  ILT2400 (Meter), SED240/T2ACT5 (Detector)


Applications:  This detector has been fitted with our proprietary UV Actinic Hazard filter giving the detector the required spectral response for taking UV optical radiation hazard measurements. Calibrated for readout in effective Watts per square centimeter. For compliance with UV hazard measurement standards that require instrumentation that can measure 0.1 microWatts per squared centimeter or better, the ILT5000 and SED240/ACT5/W UV Actinic Hazard Detector combination is required.
