Smart environmental monitoring solutions
The TunnelTech 602 Illuminance photometer monitors the average illuminance within a tunnel in accordance with Commission Internationale de l´Eclairage, (C.I.E.), publication 88, 1990 recommendations, the photometer monitors the average illuminance over a range of 0 – 20,000 lux.
The detector is a metal/glass-encased silicon diode photocell that is filtered to give a response that mimics the performance of the human eye.
The detector is perfectly linear within its measuring range and has an instantaneous response to changing light levels.
