Every version can be used as a luxmeter without classification by means of a additionally obtainable luminance attachment. The measured value (luminance) is the light effect, that comes from a reflecting or luminating surface and is measured in foot-lambert (fL) or candela per square meter (cd/m²).
This very exact luxmeter is available in class C or B, in accordance with the DIN 5032-7, DIN EN 13032-1 appendix B and CIE 69. Every model has a cosine-correction and a V(λ) adjustment. The precise measurement, delivers the illuminance of artificial light sources or even daylight. Even with head light illumination and very strong daylight you don't need any accessory.
Very high accuracies according to class B, are mainly necessary for inspection and certification purposes, which the MAVOLUX 5032 B USB delivers perfectly. Due to the measuring range with a quite high starting sensitivity of 0,01 lx measurements with very small illumination levels can be implemented. The MAVOLUX 5032 B USB includes 5 measuring ranges by means of a typical V( λ)-adjustment (f1') of < 3% and has a pluggable measuring line. Even emergency lightning can be analized easily with this. As with other products of the Gossen company, with a push of the HOLD-button the measuring values are saved and the display lightning is turned on.
The MAVOLUX 5032 C USB is mostly used as measuring instrument for standart purposes, which class C is perfect for. With the smallest of 4 measuring ranges you can begin with a starting sensitivity of 0,1 lx. The tolerance of the V(λ) adjustment f1’ < 7,5 % is significantly better, than the error limit which is anchored in class C of the DIN norm. The MAVOLUX 5032 C USB includes 4 measuring ranges and has a firmly attached measuring line.
The precision through calibration is very important for the manufacturer. A works calibration certificate or a DAkkS calibration certifacte can be acquired optionally at GOSSEN. The GOSSEN company recommends - depending on the operating conditions - a calibration interval of 12 - 24 months.
