Testo 545 Digital Lux Meter with App Connection

Overview

The Testo 545 digital lux meter is a high-performance device designed to provide accurate and reliable light measurements for a wide range of applications. Measuring illuminance from 0 to 100,000 lux, this digital lux meter is ideal for monitoring and analysing light levels, making it a valuable tool for professionals in fields including workplace lighting, commercial spaces, photography and environmental lighting.

Its light sensor is spectrally adapted to the sensitivity of the human eye (V-lambda) and cosine-corrected for accurate readings across the full range. App connectivity gives you a deeper understanding of your lighting environment, allowing you to display, log and share measurements, while hold and min/max functions make everyday measurement quick and convenient — for example, verifying lux levels across office desks and logging Smart App reports for HSE audits.

Who it is for: Facility, HSE and lighting professionals who need fast illuminance checks with App reports, time/point averages and an audible limit alarm. Need a multi-parameter air/comfort kit that includes lux? Compare the Testo 440 Lux Kit. For alternative brands, see our Fluke 941 light meter review.
