At-a-glance look at the benefits of the testo 545 light meter

The testo 545 lux meter can be used to carry out selective as well as long-term light intensity measurements. It has a built-in data logger which can save up to 3 000 readings and can be used to perform both selective and time-based averaging. The optional testo turbo printer also allows you to print out measuring data while you are on site.
The optional PC software allows you to set up up to 99 measuring sites, allocate the readings to the relevant measuring sites and connect individually saved readings to form a curve. The light profile obtained from such data provides you with a picture of the uniformity of the lighting.
