UVA intensity meter

The Sentry ST513 is a handheld UVA ultraviolet meter that measures radiation intensity up to 40 mW/cm². It offers dual-range readout in mW/cm² or µW/cm² with a backlit 4-digit LCD and automatic measurement. A magnetic back mount and tripod socket allow fixed positioning for hands-free monitoring.

UV process technicians and lab staff

Technicians who need portable UVA spot checks with data logging will find the 20-point memory and dual display practical. Buyers who require UVC or UVAB band measurement should look at other models in the ST510 series. Users needing wireless data transfer or computer logging will not find those functions here.

40 mW/cm² maximum range

The single specification that decides suitability is the 40 mW/cm² upper measurement limit. If the application regularly exceeds this intensity the meter will not capture accurate readings. For lower-intensity UVA work the range and resolution are adequate.
