Extech UV505 pocket UV-AB and LT505 pocket light meters

The Extech UV505 pocket UV-AB and LT505 pocket light meters make quality measurements of visible and ultraviolet light more convenient and accessible. The LT505 is a wide-range, general-use light meter while the UV505 meter measures ultraviolet (UV) radiation in the UVA and B ranges. These meters can be stored practically anywhere, measuring 5.3″ tall and 1.9″ wide (133 x 48 mm).

The UV505 can also aid in measuring UV light exposure related to determining the optimal window tint film; quickly measuring UV intensity from LED, halogen, HID and compact fluorescent lighting products; UV filter testing; industrial applications; UV commercial offset printing and archival preservation. The meter’s sensor has a wavelength spectrum spanning from 290 to 390 nm with cosine correction.

The LT505 delivers general use across a range of applications. It can aid in testing lighting levels to validate new lighting installations and upgrades, or help to confirm on-demand lighting systems are in compliance. The meter can measure light intensity up to 400,000 lx with 0.01 Fc/0.1 lx resolution. It provides cosine correction but is also complemented by a colour correction filter.

Both meters feature an easy-to-read backlit display showing readings and the selected unit. Useful data functions include data hold, as well as minimum and maximum readings on the LT505.
