7HCL-20 Electrochemical Hydrogen Chloride Sensor For Industrial Production Safety Detection

Usage:

The 7HCL - 20 gas sensor is mainly used to measure the concentration of hydrogen chloride (HCl) gas in the air. Hydrogen chloride is a highly corrosive inorganic acid gas, widely present in the working environments of industries such as chemical production, battery manufacturing, electroplating, and pharmaceuticals, which poses a threat to human health and equipment safety. Therefore, this sensor is crucial for ensuring workplace safety and the health of employees. It can be applied to the following scenarios:

• Industrial Production Safety Detection: Used to monitor the HCl gas concentration in industrial production processes to prevent excessive gas concentration from endangering the safety of workers and equipment, such as in the production of metal chlorides, where HCl reacts with metals, and in the production of PVC, where high - purity HCl gas is used to synthesize vinyl chloride monomers.
• Environmental Pollution Detection: Applied to the detection of HCl gas in the atmosphere, which is of great significance for environmental protection departments to monitor environmental quality, such as in the monitoring of flue gas from waste incineration and vehicle exhaust.

Features:

• High - resolution: The 2σ resolution is less than 40 ppb, which can detect very low - concentration HCl gas, enabling more accurate measurement of HCl gas concentration in the environment.
• Good Linearity: The linearity determination coefficient R² can reach 0.9996, indicating a good linear relationship between the sensor's output signal and the HCl gas concentration, which is convenient for data processing and analysis.
• Fast Response: The response time T90 is less than 60 seconds, which can quickly sense the change of HCl gas concentration, and can promptly give a response when the gas concentration changes, facilitating timely monitoring and early warning.
• Good Repeatability: The relative standard deviation RSD is less than or equal to 1%. When measuring the same concentration of HCl gas, the sensor can obtain relatively stable measurement results, with high reliability and stability.
• Zero - bias and Short Power - on Equilibration Time: The bias voltage is 0, and the power - on equilibration time is less than or equal to 50 seconds, which simplifies the circuit design and can quickly enter the working state, improving the efficiency of use.
• Strong Overload Resistance: It can withstand an overload of 50 ppm HCl gas, and the signal will not decrease. When the HCl gas concentration briefly exceeds the measurement range, the sensor can still work normally without being damaged, with strong anti - interference ability.
• Good Selectivity1: It has large responses to NO₂ and H₂S, and is hardly interfered by other gases, which can effectively avoid false alarms caused by other gases and ensure the accuracy of measurement results.
