Uv Sensor

RUGGED, SELF-CLEANING HOUSING Sensor features an anodized aluminum body with fully-potted electronics. The dome-shaped sensor head minimizes errors by shedding dust and water for a selfcleaning performance. HIGH QUALITY CABLE Pigtail-lead sensors feature on IP68, marine-grade stainless-steel cable connectors attached directly to the sensor head to simplify sensor removal for maintenance and recalibration. CALIBRATION TRACEABILITY Apogee UV-A series sensors are calibrated through side-by-side comparison to the mean of four transfer standard UV sensors under sunlight (clear sky conditions) in Logan, Utah. The transfer standard UV-A sensors are calibrated though side-by-side comparison to an Apogee model PS-300 spectroradiometer under sunlight (clear sky conditions) in Logan, Utah. The PS-300 is calibrated with a quartz halogen lamp traceable to the National Institute of Standards and Technology (NIST).
