Testo 545 – Digital Lux Meter with App Connection
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.
With the Testo 545 Lux meter, you can measure the illuminance of all common light sources - quickly, easily, and precisely. The measuring instrument is compatible with almost all commercially available LEDs and thus ensures you a wide range of applications.
By automatically calculating the time and point average value, the Lux meter shows you all relevant information at a glance.
The Testo 545 is perfectly complemented by the Testo Smart App which is free to download for Android and iOS. Providing a great user experience, the app has a clear graphical presentation of readings and simple, fast menus. The measurement menus for numerous applications provide optimum support in configuring and carrying out the measurement. You can also create digital measurement reports including photos as PDF/CSV files on-site which can be sent via e-mail.
