13 Feb 2008 Spectrum Detector, Inc. Introduces First Commercially Available TRAP Radiometers And Joulemeters TRAP digital radiometers & joulemeters set new stds in measurement uncertainty: <1% on multiple points across spectrum. Systems based on “wedge” TRAP concepts pioneered at NIST Boulder–where the technology plays critical role in NIST spectral cal transfer stds. Entire system is contained within a single, compact, USB-powered probe housing. Connect probe to PC via USB port & measure using Labview software. Ideal for ultra-precise measurement application from DUV to Far IR. Provides NIST-level gold std for in-house cals. |
