Light intensity in workplaces must
fulfill minimum values and have to
be checked regularly. Using
software, a site list can be stored
and individual luminous intensity
values can be connected to form
a curve. This light profile provides
information on the uniformity of
the lighting.

Measures light intensity at the workplace
testo's 540 sensor is adapted to
the eye's spectral sensitivity.
testo 540 is therefore ideal for
measuring light intensity in the
workplace. Practical and small, it
fits all pockets.
• Sensor adapted to spectral
sensitivity of the eye
• Hold function and max./min.
