Specification Sheet
The SE-202 is an amplified photometric sensor with a 0 to 2500 mV output and a 0-5000 lux range. The sensor features a rugged, aluminum housing that is fully-submersible and is built to withstand harsh conditions, and high-quality cable terminating in pre-tinned pigtail leads for easy connection to dataloggers and controllers. 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.
