Overview

Gasboard-2522 is a QCL-based TDLAS N2O sensor designed for Euro 7 vehicle exhaust monitoring, with high selectivity, sensitivity and response of ≤3 seconds. A quality optical probe, proprietary cell, modular design and RS485 calibration suit automotive, environmental and laboratory applications.

Key Features

  • QCL-based narrow-band laser absorption spectroscopy with ultra-high sensitivity for N2O measurement, resistant to interference from other gases, humidity, and particulate matter.
  • Ultra-fast response time of ≤ 3 seconds for real-time monitoring.
  • Full-scale linear digital output for consistent, repeatable, and traceable measurement.
  • High-performance optical probe for stable operation and long service life.
  • Modular design for easy system integration and future upgrades.
