Illuminance is a crucial factor for productivity, well-being, and health, especially in workplaces. Too bright light sources can cause glare, while too dim lighting can lead to concentration issues and headaches. With the testo 545 lux meter, you can quickly, easily, and accurately measure the illuminance of all common light sources. The device is compatible with nearly all commercially available LEDs, ensuring a wide range of applications. By automatically calculating the temporal and point average, the lux meter provides you with all relevant information at a glance. The testo 545 is perfectly complemented by the testo Smart App. This app not only allows you to configure the measuring device but also facilitates the display and storage of measurement values as well as documentation in a particularly convenient way. The app also turns your smartphone into a second display.
