The SU-100 is an un-amplified analog sensor with a voltage output. The sensor incorporates a photodiode that measures combined UVA and UVB radiation. Typical applications include UV radiation measurement in outdoor environments (sensor is not recommended for long-term continuous outdoor deployment), laboratory use with artificial light sources (e.g., germicidal lamps), and monitoring the filter ability and stability of various materials. Sensor includes IP68 marine-grade stainless-steel cable connector 30 cm from head to simplify sensor removal and replacement for maintenance and recalibration.
