Road Lighting Illuminance and Luminance Meter

Precision photometer set with a cosine corrected lux sensor and a luminance head for measuring street light levels on roads and tunnels. Used in highway safety audits and lighting acceptance tests.

Specification

The cosine-corrected illuminance probe records lux on the road surface or at the lamp column, and the luminance head measures cd/m2 at 2 deg field. Measurements verify uniformity and average levels for traffic safety. Memory stores readings by location.

Features

• Illuminance 0.01 to 200,000 lux
• Luminance head 2 deg field of view
• Cosine and V(lambda) corrected sensor
• Data logging with timestamp
• Tripod mount for repeatable placement
