Applications

The MAVOLUX 5032 illuminance and luminance meters are handy, easy to use and high precision
measuring instruments. They allow the accurate measurement of the illuminance in lx or fc.
Combined with the Luminance Adapter, available as optional accessory, the Mavolux 5032 can also
be used for measuring luminance in cd/m² or fL.
The light sensor is color corrected, i.e. its spectral responsitivity has been matched to that of the
human eye V(λ). The accuracy of that V(λ) matching is the main difference between the two types
Mavolux 5032 C and Mavolux 5032 B.
The accuracy classes for illuminance meters have been defined in the Standard Specifications DIN
5032, Part 7. (CIE 69) Consequently, the Mavolux 5032 C complies with Class C, Mavolux 5032 B
complies with Class B (CIE 69). Suitable cosine correction is integrated in the light sensor probe, so
that oblique incident light will be measured accurately. Consequently, the MAVOLUX 5032 C complies
with Class C, MAVOLUX 5032 B complies with Class B.
All the important types of light can be measured with high precision, without the necessity to apply any
additional correction factors.
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 measurement data memory with 100 locations, which can be
read and processed direct with the keys and the display but also through the integrated USB Port and
the Standard Software supplied with the meters.
