Series 900 can determine any gas species with potential to be derivatized as well as quantify ppb/ppm level impurities in industrial processing and electronic gases, such as N₂, N₂O, NF₃, and CxHy. It has continuous, digital readout, colorimetric detector, internal sample pump, and adjustable flow rate and light intensity. Unit is self-contained in 19 in. rack-mount design. Analyzer is engineered for quantifying trace amounts of toxic gases in industrial gas applications.
