Due to its outstanding accuracy in accordance with class B, the MAVOLUX 5032 B USB is used primarily for certification and inspection applications. An additional measuring range with high initial sensitivity of 0.01 lx makes it possible to measure extremely small light intensities. This even permits reliable measurement of emergency lighting. After pressing the HOLD key, the measured value is saved to memory and display illumination included with this version is activated, making it possible to read the display in dark environments. Adaptation to the spectral brightness sensitivity of the human eye V(λ) is highly precise with minimal deviation of just f1‘ < 3 %.
Both variants can be used as unclassified luminance meters with the help of an optional luminance attachment with an acceptance angle of 15°. Luminance is measured in candelas per square meter (cd/m²) or footlamberts (fL), and defines the perceived brightness of a back-lighted or reflecting surface.
At GOSSEN, great emphasis is placed upon reliability by means of calibration. For purposes of documented evidence, a factory calibration
certificate or a DAkkS calibration certificate can be ordered along with either variant. Depending on how the meter is used, we recommend a calibration interval of 12 to 24 months.
MAVOLUX 5032 B USB Specifications
MAXIMUM PRECISION
Classified measurement of illuminance in lx or fc in accordance with class B or class C per DIN 5032-7, appendix B of DIN EN 13032-1 and CIE 69.
COSINE CORRECTIONS
The luminosity of a flat measuring surface is proportional to the cosine of the incident angle of light. This relationship is taken into consideration by the sensor during evaluation.
NON-VOLATILE MEMORY
100 measured values can be saved, retrieved or transmitted to a PC via the integrated USB port. Average illuminance values can also be calculated as a result.
BROAD MEASURING RANGE
High initial sensitivity and a resolution of 0.01 lx or 0.001 fc for the MAVOLUX 5032 B USB, right on up to large illuminance values of 199,900 lx or 19,990 fc.
SIMPLE EXPANSION OF FUNCTIONS
Unclassified measurement of luminance in cd/m2 or fL is made possible by the optional luminance attachment.
An additional adapter disc prevents erroneous measurements due to incidence of light from the side.
CONVENIENT EVERYDAY USE
Simple operation, easy to read display, compact design, protection during transport in a high quality aluminum case.
V(λ) ADAPTATION
The spectral sensitivity of the silicon photodiode is color corrected and corresponds to the spectral brightness sensitivity of the human eye V(λ). The quality of this adaptation represents a significant difference between the class B and class C variants.
COMPUTER-AIDED MEASUREMENT
The meter's continuous operating mode is assured thanks to power supply via the USB port. Meter control, as well as reading, display and storage of measured values, is managed with GLUX 2 software, included in the delivery contents.
