Nashua, NH — Extech Instruments has launched two compact light me- ters, designed to make quality meas- urements of visible and ultraviolet (UV) light more convenient and ac- cessible. The LT505 is a wide-range, general-use light meter, while the UV505 measures UV radiation in the UVA and B ranges. Unlike other me- ters, the new 505 can be stored prac- tically anywhere, as it is 5.3 x 1.9 in. (13.3 x 4.8 cm) in size. The UV505 meter can perform


routine monitoring of sunlight UV levels for anyone vulnerable to ex- tended UV exposure, such as con- struction workers, contractors and surveyors, agriculture, forestry, landscaping and fishing workers. The pocket-sized UV505 meter’s


sensor has a wavelength spectrum spanning from 290 to 390 nm with co- sine correction. The UV505 measures the intensity of ultraviolet radiation in energy (watts) per square centime- ter received per second in two ranges — 1 to 3,999 µW/cm2 and 0.01 to 40 mW/cm2 with high resolution. The LT505 is a robust light


meter for general use across a range of applications. The LT505 can aid in testing lighting levels to validate new lighting installations, upgrades or help to confirm on-demand light- ing systems are in compliance. For occupational safety and for safety in commercial facilities, lighting tests should be performed in parking garages, warehouses, corridors, and areas with limited monitoring. The LT505 can measure light intensity up to 40,000 fc (400,000 lux) with 0.01 fc (0.1 lux) resolution. Like the

UV505 pocket UV-AB light meter. Both meters contain an easy-to-


read backlit display that shows read- ings and the selected unit. Useful data functions include data hold, as well as minimum and maximum readings on the LT505. A zero func- tion allows the user to quickly reset the meter to zero or calibrate the meter (LT505). Both meters offer auto-power-off to preserve battery life. A optional tripod mount allows users to set up the meter with consis- tent placement to avoid variability in


routine measurements. Contact: Extech Instruments, 9
