Testo 545 Digital Luxmeter
Product Datasheet
Product Overview
The testo 545 is a digital luxmeter designed for precise and efficient measurement of illumination levels (lux) according to the V-lambda curve, suitable for all common light sources. It offers broad application possibilities, including compatibility with LED lighting (excluding monochromatic blue LEDs).
Key features include:
- Simple, fast, and accurate measurement of light intensity (lux)
- Compatibility with most commercially available LED diodes
- Quick configuration via the testo Smart App
- Graphical display of measurement progress
- Second screen functionality and data storage within the testo Smart App
- Acoustic alarm for exceeding limit values
- Calculation of spot and time-weighted average values
Benefits of Proper Lighting: Illumination is a critical factor for productivity, comfort, and health in workplaces. Overly bright light can cause glare, while insufficient light impairs concentration and can lead to headaches. The testo 545 helps ensure optimal lighting conditions.
Testo Smart App Integration: The testo 545 is complemented by the testo Smart App, which allows for easy configuration of the measuring instrument, display and storage of measured values, and convenient documentation. The app transforms your smartphone into a secondary display for the instrument.
