The Testo 545 Compact Lux meter can measure the illuminance of all common light sources easily, quickly and precisely to ensure productivity, performance and health in workplaces.
Illuminance is a decisive factor for productivity, well-being and health, especially in workplaces. Light sources that are too bright dazzle, while those that are too dark can lead to concentration problems and headaches.
The Testo 545 is entirely complemented by the Testo Smart App. This not only allows you to configure the measuring instrument, display and store the measured values, and document them in a particularly convenient way. The App also turns your smartphone into a second display.
