Sunvou vs Niox: A Comparison

Written By FIRAT ULAS ATALAY

Product Comparison: NIOX VERO ("The 1") vs. SUNVOU-CA2122 ("The 1+2")

  1. Product Model:

    • NIOX VERO: "The 1"

    • SUNVOU-CA2122: "The 1+2"

  2. Sensor Technology:

    • NIOX VERO uses a Micro Amperometric Electrochemical Sensor.

    • SUNVOU-CA2122 uses a Nano Coulombic Electrochemical Sensor.

  3. Biomarkers:

    • NIOX VERO measures Nitric Oxide (NO).

    • SUNVOU-CA2122 measures Nitric Oxide (NO), Carbon Monoxide (CO), and Hydrogen Sulfide (H2S).

  4. NO Parameters:

    • NIOX VERO measures FeNO.

    • SUNVOU-CA2122 measures FeNO50, FeNO200, CaNO, and FnNO10.

  5. Detection Options:

    • NIOX VERO supports Online detection.

    • SUNVOU-CA2122 supports Online, Offline, and Tidal detection options.

  6. Quality Controls:

    • NIOX VERO requires a Qualified User for quality control.

    • SUNVOU-CA2122 offers Qualified User, Standard Gas, and Self-calibration options for quality control.

  7. NO Measurement Range:

    • NIOX VERO has a range of 5-300 ppb for NO measurements.

    • SUNVOU-CA2122 has a broader range of 0-3000 ppb for NO measurements.

  8. Display & Power:

    • NIOX VERO is equipped with a 3.5-inch LED Screen and uses a Rechargeable Battery.

    • SUNVOU-CA2122 connects to a PC for display and uses an AC Adapter for power.

  9. Linearity:

    • NIOX VERO has a linearity of R² ≈ 0.998.

    • SUNVOU-CA2122 has a linearity of R² ≥ 0.99.

  10. Endogenous Interference of NO:

    • For NIOX VERO, 13 interfering gases were tested, and the response value of a few gases exceeded 50 ppb. Ethanol caused the most interference, which could potentially invalidate or disable the sensor.

    • For SUNVOU-CA2122, 16 interfering gases were tested. Methyl mercaptan interfered at 4 ppb, while other gases caused interference at levels lower than 3 ppb. Ethanol also caused interference, which may reduce the test value instantaneously; therefore, caution is advised when using it.
