TunnelTech 601 Luminance Photometer

Codel's innovative TunnelTech 601 Luminance Photometer has been designed to successfully monitor the average luminance of a tunnel entrance as well as it's surroundings. Made in accordance with Commission Internationale de l?Eclairage, (C.I.E.), publication 88, 1990 recommendations, the photometer monitors the average luminance within a 20 degree angle over a standard range of 0 ? 6,500 cd/m2. It incorporates a perfectly linear detector that has a metal/glass encased silicon diode photocell which is filtered to give a response that mimics the performance of the human eye.
