Product Features:

  • Professional 3-electrode Electrochemical Technology: Adopts optimized three-electrode sensing structure to eliminate electrode interference, ensuring highly linear and stable output for nitric oxide detection.
  • Ultra-fast Response Speed: T90 response time ≤ 15 seconds, realizing rapid real-time tracking and feedback of NO concentration dynamic changes.
  • High Detection Accuracy & Stability: Standard sensitivity of 0.55±0.11 μA/ppm, extremely low baseline offset and temperature drift, maintaining long-term consistent measurement accuracy.
  • Strong Overload Resistance: Supports instantaneous high concentration overload up to 1500 ppm, effectively preventing sensor saturation and damage caused by sudden gas concentration surge.
  • Low Cross Interference: Optimized gas filtering performance, zero response to conventional interfering gases such as CO and H2S, with controllable interference from NO2 and SO2.
  • Wide Environmental Adaptability: Stably operates in wide temperature, humidity and pressure range, adapting to complex outdoor and industrial working environments.
  • Standard Miniature Structure: Classic 7-series small-size design, lightweight (approx. 5g), no installation orientation limitation, convenient for embedded PCB installation.
  • Long Service Life: Provides 24-month stable service life in conventional ambient air, meeting long-term continuous monitoring requirements.

Product Applications:

  • Ambient Air Quality Monitoring: Used for atmospheric nitric oxide pollutant detection in urban environmental monitoring stations, community air quality stations and municipal environmental inspection systems.
  • Industrial Flue Gas Monitoring: Applied in thermal power plants, boiler flue gas, industrial combustion equipment and factory exhaust gas emission monitoring systems for NO concentration detection.
  • Automotive Exhaust Detection: Embedded in vehicle exhaust analyzers and motor vehicle environmental detection equipment to monitor nitric oxide content in exhaust emissions.
  • Industrial Safety Monitoring: Suitable for real-time gas detection in chemical workshops, combustion reaction processes and industrial toxic gas safety monitoring scenarios.
  • Portable Gas Detectors: Widely matched with handheld industrial gas detectors and portable environmental monitoring instruments for on-site rapid NO concentration testing.
