The SE-100 Photometric sensor is a self-powered lux sensor with a range of 0-200 klux over a 0 to 200 mV range. The sensor features a rugged, aluminum housing that is fully-submersible and is built to withstand harsh conditions. The sensor cable includes an IP68 marine-grade stainless-steel cable connector to simplify sensor removal and replacement from permanent installations for maintenance and calibration. Typical applications of photometric sensors include measuring light levels for human vision in offices, sports arenas, hospitals, museums and more.
