Portable Gas Analyzer

The instrument should be placed in a safe location to prevent damage from falling or severe vibration. Before using the instrument, please charge it promptly. During charging, simply plug the power cord into a 220 V socket – there is no need to turn on the power switch; the device will begin charging automatically. The typical charging time is more than 20 hours. When not in use, the instrument should be placed in a dedicated packaging box and stored on a test bench or instrument rack to protect it from dust and moisture. The instrument should be calibrated once per year using standard gases. Calibration may be performed at the manufacturer or an authorized third-party facility to ensure accuracy. When the concentrations of SO₂, H₂S, or CO in the measured gas are elevated, the gas remaining in the gas transmission tube should be purged before proceeding with the next measurement. When the SO₂, H₂S, or CO concentrations measured by the monitoring device exceed the normal range, it is recommended to perform two additional measurements to confirm the results. According to Section 8.2 of the IEC 60480-2004 standard: Maximum acceptable impurity quality levels: total decomposition products ≤ 50 μL/L; or (SO₂ + SO₂F₂) ≤ 12 μL/L; or HF ≤ 25 μL/L.
