CR1000

GasmetTM CR-Series includes quantitative multicomponent gas analyzers for laboratory research applications. The GasmetTM CR1000 incorporates a Fourier transform infrared, FTIR spectrometer, a temperature controlled sample cell, and signal processing electronics. Liquid nitrogen cooled MCT detector has the highest performance available.

The GasmetTM CR1000 is designed for speed and reliability. The single pass sample cell provides high optical throughput and very quick response times. As the sample cell is available for short path lengths only, it is optimal for percentage concentrations. Typically CR1000 is used for process measurements and catalyst research applications. The rugged stainless steel sample cell is typically heated up to 180 ºC. Higher temperatures are available by special request.

CR-models scanning and analysis speed can be configured according to customers need. The following table tells the difference in between GasmetTM CR-models:
