 The ILT73NB UVB Light Meter/Radiometer directly measures the UVB output from TL-01 narrow-band UVB lamps. It comes with calibration at 313 nm.   Please see spectral response curve below.

 

The Model ILT73-NB is designed for measurement of TL-type narrow band UVB lamp.  For broadband UVB sources, see Model ILT73CE.

 

The detector is filtered for a spectral range of 260-325 nm and comes with a calibration at 290 nm for broadband UVB-only sources (ILT73CE) or 313 nm for narrowband TL-type UVB sources (ILT73-NBCE).

 

Both models have a measurement range of 0.1-19.99 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 4½ 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.
