MultiGas™ 2030 HS is a high speed, high resolution FTIR based gas analyzer designed to monitor automobile, diesel, locomotive, and catalyst combustion exhaust emissions at 5 measurements per second (5Hz). The MultiGas™ 2030 HS gas analyzer is composed of a high speed 0.5 cm-1 process-hardened FTIR spectrometer. This FTIR spectrometer incorporates a patented 5.11 m high-optical-throughput 200 mL gas sampling cell capable of 100 L/m flow rate no backpressure or noise that would degrade the quantitative measurement. The analyzer generally incorporates a high sensitivity liquid nitrogen cooled MCT detector that can maintain cryogenic temperatures for up to 12 hours on a single charge and up to 3-4 days with an additional 5L external dewar. The system is delivered complete with easy to use software and system diagnostics, calibration, installation and training.
