Pocket-sized and easy to use, the Testo 540 is excellent for checking light levels in offices and other similar applications.

Specially adapted to the sensitivity of the human eye, the Testo 540 quantifies the level of light in an area in lux. To use, simply hold the integrated sensor as close as possible to a light source and the 540 will then gain a reading.

This tester also includes additional functionality such as data hold (temporarily stores the last value taken on the screen) and a MAX/MIN function which calculates the maximum and minimum value taken over a period of time.
