Product Overview

Gasboard-9809 is a high-end engine exhaust emission analysis system designed for NH3 and N2O measurement to address the newly introduced NH3 & N2O emission monitoring requirements under the latest regulations such as Euro 7.

The system employs TDLAS technology for precise NH3 measurement and QCL-based laser spectroscopy with ultra-high sensitivity for N2O detection, delivering high measurement sensitivity, strong resistance to interference from background gases, and fast response for real-time online monitoring under dynamic engine operating conditions.

Gasboard-9809 features independent sampling, pretreatment, and data analysis units, ensuring stable system operation and reliable measurement performance. The system can be deployed alongside existing Euro 6 exhaust emission analysis systems, enabling NH3 and N2O measurement without restructuring existing exhaust testing setups and supporting a smooth transition toward Euro 7 compliance.

Typical applications include vehicle type-approval testing, performance verification, and emission research during engine and vehicle R&D, where NH3 and N2O emission measurement is required to support Euro 7 emission compliance.
Features

• Compliance with major international emission testing standards, including Euro 7 and CFR 1065, for light- and heavy-duty vehicle certification testing.
• High-sensitivity, accurate NH3 and N2O measurement, supporting a wide range of fuels, vehicle types, and test conditions.
• Strong resistance to cross-interference from background gases, such as CO2 and H2O, under complex exhaust conditions.
• Independent system design, allowing deployment alongside existing Euro 6 exhaust emission analysis systems to support Euro 7 testing requirements.
• Real-time data display and remote control, compatible with automated exhaust emission testing platforms.
