The MAVOLUX 5032 illuminance meters are handy, easy to use and high precision measuring
instruments. They allow the accurate measurement of the illuminance in the unit lx or fc.
Combined with the Luminance Attachment, available as optional accessory, the MAVOLUX 5032 can also
be used for measuring luminance in the unit cd/m² or fL.
The light sensor is color corrected, i.e. its relative spectral responsivity has been adapted to that of the
human eye
V(

). All the important types of light can be measured with high precision, without the necessity
to apply any additional correction factors.
The accuracy of that
V(

) adaptation is the main difference between the two types MAVOLUX 5032 C and
MAVOLUX 5032 B. The quality classes for illuminance meters have been defined in the Standard
Specifications DIN 5032, Part 7. Consequently, the MAVOLUX 5032 C complies with Class C, MAVOLUX
5032 B complies with Class B (DIN 5032, part 7 and 8).
The light collector with circular orifice in the photometer head has integrated cosine correction, so that
oblique incident light will be measured accurately.
Both MAVOLUX types allow measuring very high intensity light (daylight, headlights) without additional
accessories. Especially the MAVOLUX 5032 B having an initial sensitivity of 0.01 lx is ideally suited for
measuring extremely low light intensities, such as emergency lighting.
The instruments are provided with a measuring value memory with 100 data spaces, which can be read
and processed directly by the keys and the display but also through the integrated USB Port and the
Standard Software supplied with the meters.
