The Spectroline DSE-2000 from Spectronics Corp. measures both visible and black light. CE-approved and MIL- and ASTM-compliant, it is designed for nondestructive testing and quality control inspections. The system includes the DSE-100X digital readout unit and two interchangeable sensors: the DIX-555A visible-light sensor and the DIX-365 black-light sensor. The system provides accuracy better than ±5% traceable to NIST over its entire measurement range. The components come in a lightweight plastic case.
