    Overview


    The nitric oxide (NO) gas sensor is designed for accurate nitric oxide detection and concentration monitoring in industrial processes, chemical plants, and environmental monitoring systems. It offers a sensitivity of 400 ± 100 nA/ppm, a response time of ≤30 seconds, and a resolution of 1 ppm for detection ranges up to 1000 ppm. The 5000 ppm range provides a resolution of 2 ppm.

    NO sensor with multiple detection ranges


    Multiple Detection Ranges

    • Offers optional detection ranges of 0–50 ppm, 0–250 ppm, 0–1000 ppm, and 0–5000 ppm to meet different gas monitoring requirements.
    • Adopts high-precision integrated circuits for accurate signal processing and improved measurement reliability.
    • The nitric oxide (NO) gas sensor uses a three-electrode electrochemical detection principle for sensitive and reliable nitric oxide detection.
    NO sensor with fast response time

    Strong Anti-Interference Capability

    • Its signal processing design helps reduce interference and maintain stable performance in industrial gas detection applications.
    • The NO gas sensor features short-circuit and reverse-polarity protection, with long-term stability of less than 2% signal change per month.
    • With a response time of ≤30 seconds, the NO sensor enables timely monitoring of nitric oxide concentrations.

    FAQs

    Q1: What is a nitric oxide (NO) gas sensor used for?
    A1: A nitric oxide (NO) gas sensor detects and measures NO concentrations in industrial processes, chemical plants, air pollution monitoring, and industrial emission detection. It helps monitor nitric oxide levels for environmental monitoring and gas safety applications.

    Q2: What is the detection range of the SISCO NO gas sensor?
    A2: The SISCO NO gas sensor (Model: SISCO-GS-S4NO) offers four optional detection ranges: 0–50 ppm, 0–250 ppm, 0–1000 ppm, and 0–5000 ppm. Users can select the appropriate range according to their gas monitoring requirements.

    Q3: How does an electrochemical NO gas sensor work?
    A3: The SISCO nitric oxide gas sensor uses a three-electrode electrochemical detection principle to measure nitric oxide concentrations. It provides a response time of ≤30 seconds, a sensitivity of 400 ± 100 nA/ppm, and a resolution of 1 ppm for the 0–50 ppm, 0–250 ppm, and 0–1000 ppm ranges.

    Tips: What factors should be considered when selecting a nitric oxide (NO) gas sensor?

    When selecting a nitric oxide (NO) gas sensor, consider the required detection range, resolution, response time, operating temperature, and humidity conditions. The SISCO-GS-S4NO offers optional ranges from 0–50 ppm to 0–5000 ppm, a response time of ≤30 seconds, and an operating temperature range of -30°C to 50°C, making it suitable for different industrial gas monitoring and air pollution detection requirements.
