This nitrogen dioxide transmitter utilizes an imported electrochemical sensor core, known for its rapid response and strong anti-interference capabilities. The module’s performance is enhanced through proprietary compensation algorithms and multi-point calibration, resulting in high accuracy (±3% FS), repeatability (±2%), and long-term stability. Its design is tailored for reliable monitoring of NOâ‚‚ concentrations in demanding settings.
The device communicates via an RS485 interface using the industrial-standard Modbus-RTU protocol, allowing for easy integration into Building Management Systems (BMS), Industrial PLCs, and data acquisition systems. The wall-mounted enclosure provides a high level of environmental protection, making it suitable for installation in ventilation ducts, industrial facilities, and outdoor air quality monitoring stations where consistent, accurate gas data is critical.
