Cubic Sensor and Instrument Co., Ltd
Cubic Instruments - Model Gasboard-2522 -Quantum Cascade Lasers N2O Sensor
Gasboard-2522 is a high-precision N2O gas sensor based on Tunable Diode Laser Absorption Spectroscopy (TDLAS) and employing a quantum cascade laser (QCL) source. It is designed for highly selective and sensitive N2O measurement in automotive exhaust emission monitoring under the latest Euro 7 performance requirements. Gasboard-2522 integrates a high-quality optical probe with a proprietary gas cell to deliver high measurement accuracy, high sensitivity, strong resistance to cross-gas interference, and long-term stable operation. Featuring a modular design, Gasboard-2522 supports easy installation and system integration. Calibration and configuration are available via an RS485 communication interface. Applications include automotive exhaust emission monitoring, environmental monitoring, and laboratory research.Most popular related searches
