FTX-ONE

FTIR Exhaust Gas Analyzer

FTX-ONE is a fast response and compact size FTIR analyzer for the simultaneous measurement of multiple components of engine exhaust gases.

The FTX-ONE offers a 5Hz sampling rate and simultaneously measure the concentrations of multiple components including NH₃, CH₄, and CO₂, from un-diluted exhaust gas using the Fourier Transform Infrared (FTIR) method in combination with multivariate analysis algorithm.

Segment: Automotive

Division: Emission Measurement Systems

Manufacturing Company: HORIBA, Ltd.

Low sample flow rate but fast response.
Whilst maintaining high accuracy by the use of a high performance compact gas cell.
Multi-point exhaust sampling and ideal for catalyst evaluation in combination with a simulated exhaust gas generator.
Approx. 50%^*2 smaller footprint and reduced weight in comparison to a conventional laboratory FTIR.
More Flexibility in cell layout and easier access for maintenance.
At the Core of the Instrument - In-House Knowledge
The analyzer is the core of an emission measurement system and the key to accurate measurement. HORIBA maintains excellent quality by manufacturing analyzers “in-house” and designs for operation & maintenance efficiency.
