The ILT73 UVB Radiometer directly measures the UVB output from a multitude of conventional UVB sources (DC - 60Hz).

The Model ILT73-NB is designed for measurement of TL-type UVB lamps and the Model ILT73 is designed for broader UVB sources.

The detector is filtered for a spectral range of 275-325 nm and comes with a calibration at 290 nm for broadband UVB sources (ILT73) or 313 nm for narrowband TL-type UVB sources (ILT73-NB).

Both models have a measurement range of 1-19.99 mW/cm². Readings are taken using a single button, and the meter shuts off automatically after 2 minutes to preserve the life of the 9 volt battery.

The 4?digit meter is enclosed in a removable cushioning boot (not shown) that protects the unit from accidental falls and acts as an instrument stand or hanger.

Each system is individually calibrated to NIST-traceable standards and is supplied with an appropriate certificate.
