Gossen M502B Mavolux 5032 C Base Illuminance Meter

M502B Includes Only:

• M502B Mavolux 5032C Base
• Battery
• Operating instructions
• Calibration protocol

Features:

• Maximum reliability: Classified measurement of illuminance in Ix or fc in accordance with class C per DIN 5032-7, appendix B of IEC 13032-1, and CIE 69.
• Precise Measured Values: Accuracy amounts to + 3% + 1 digit of the display value.
• Broad measuring range: High initial sensitivity and a resolution of 0.1 Ix or 0.01 fc, right on up to large illuminance values of 199,900 Ix or 19,990 fc.
• Calibration Capability: As an option, the accredited GOSSEN Light Lab can issue a factory or a DAkkS calibration certificate for measuring equipment monitoring in accordance with DIN EN ISO 9001:2008.
• V(A) matching: The spectral sensitivity of the silicon photodiode is color corrected and corresponds to the spectral brightness sensitivity of the human eye V(A).
• Cosine correction: 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 receiver during evaluation.
• Non-volatile memory: 100 measured values can be saved and retrieved.
• Convenient everyday use: Simple operation, easy-to-read display, compact design.

Due to its class C accuracy, this meter is used primarily as an industrial measuring instrument for planning, installing, inspecting, and monitoring lighting systems, as well as for the assurance of compliance with specified lighting conditions. Its four measuring ranges with automatic or manual range selection cover a broad span from 0.1 to 199,900 lx with an accuracy level of ± 3% ± 1 digit. V(λ) matching deviation, which amounts to f1' < 7.5%, is considerably better than the permissible error limit for class C specified in the standards.
