Extech LT45 Colour LED Light Meter
Extech LT45 Colour LED Light Meter is designed for measuring and checking environmental light levels across a wide range of workplaces and public settings. It measures standard lighting as well as white, red, yellow, green and blue LED light sources. Users can select Lux or Foot-Candle (Fc) units to suit the task and reporting method.
With a 4000-count display, the meter supports clear measurement work across lighting levels up to 400,000 Lux or 40,000 Fc. Min, Max and Average functions help users review changing light conditions, while cosine and colour corrected measurements support work with the specified light sources. The Extech LT45 Colour LED Light Meter can also store and recall up to 99 readings, making it easier to record measurements during inspections.
Workplace lighting can be checked to help verify adequate illumination for assigned tasks and support lighting compliance work. This makes the meter suitable for offices, manufacturing plants, warehouses, university campuses, schools and hospitals. A separate light sensor is supplied with a protective cover and a coiled cable that extends to 59 inches (1.5 m), while the supplied hard carrying case helps keep the instrument and its accessories together.
