SU-200 Specification Sheet
The SU-202 is an amplified UV-A sensor with a 0 to 2.5 V output and high-quality cable terminating in pre-tinned pigtail leads for easy connection to dataloggers and controllers. The sensor offers a low-cost option for detecting UV radiation from 300 to 400 nm and is calibrated in energy flux units of Watts per square meter. Typical applications include monitoring the filtering ability and stability of various materials, measuring UV-A radiation in outdoor environments and laboratory use, and monitoring UV radiation in horticultural operations environments. Sensor includes IP68 marine-grade stainless-steel cable connector to simplify sensor removal and replacement for maintenance and recalibration.
