getSpec NIR 0117 standard - peltier cooled spectrometer with USB Interface for NIR Applications up to 1700 nm

Request for information

The getSpec NIR 0117 standard with USB interface is a complete NIR spectrometer with a Peltier-cooled InGaAs diode array detector on a PC card. The spectrometer has no flexible or adjustable parts and is completely maintenance-free. This guarantees a high degree of stability of the NIR calibrations models. High detector sensitivity and Peltier cooling of the InGaAs diode array also permit high speed measurements in the millisecond range.

Owing to the flexible fiberoptical coupling, the spectrometer can be used for various different applications in process analysis, mobile analysis or quality assurance. In connection with chemometric methods, it is well suited for quantitative as well as qualitative analysis.

In addition to the SPEC32 software that is included in delivery, a GRAMS®/32 package and a MyInstrument driver are available optionally. Using the driver the spectrometer can directly run under GRAMS®/32 software. This allows you to build your chemometric models for quantitative or qualitative analysis easily.
