FTX-ONE-CS/RS
FTIR Exhaust Gas Analyzer - Direct Measurement Type
The FTX-ONE CS/RS is a compact, fast-response FTIR analyzer designed for direct measurement of engine exhaust gas. Equipped with a high-performance optical cell and multivariate analysis, it measures up to 28 exhaust gas components—such as NH₃, CO₂, and CH₄—at 5 Hz sampling rate using Fourier Transform Infrared technology.
Why Choose FTX-ONE-CS/RS
Ultra-Fast Detection – Achieves approximately 1.5-second response for difficult-to-measure gases like ammonia.
-
Low Sampling Flow – Uses minimal exhaust draw to avoid impact on engine combustion or catalyst behavior.
-
Highly Compact Design – Occupies about half the space and weight of conventional FTIR systems, offering greater lab flexibility.
-
Versatile Dual Model – The RS variant adds THC and O₂ detection, enabling rich insights like AFR and fuel consumption from one unit.

Rapid Exhaust Analysis
Captures fast-changing emission profiles accurately during dynamic engine testing.
Minimal Flow Impact
Ensures precise measurement without disturbing engine or catalyst operation.
Space-Efficient Build
Facilitates flexible lab integration and repositioning with ease.
Expanded Measure Capabilities
Delivers richer emissions and fuel-consumption insights in a single integrated unit.
