Product Overview<\/b><\/strong><\/h3>\n

The A-Type Intelligent Dual-Channel Constant-Flow Air Sampler is designed for the collection of gaseous and vapor-phase air pollutants such as SO\u2082 and NO\u2093. The device is compact and portable, providing stable flow rates while significantly reducing labor intensity. Equipped with a high-performance 32-bit processor, dot-matrix LCD, and advanced sensors, it ensures precise, stable data collection. It is widely used in environmental monitoring, occupational hygiene, labor protection, safety supervision, military, research, and education.<\/p>\n

Working Principle<\/b><\/strong><\/h3>\n

The sampler employs a dual independent sampling system with electronic flow meters and high-performance diaphragm pumps to maintain constant flow. A built-in temperature control system prevents freezing of sampling solutions, while dust filters protect the pump and gas pathways. During sampling, the device automatically calculates cumulative sample volume and converts it to standard conditions based on ambient temperature and pressure, ensuring accurate and reliable data.<\/p>\n

Key Features<\/b><\/strong><\/h3>\n
    \n
  • Dual-Channel Sampling<\/strong>: Collects two gases or parallel samples simultaneously, with independent control for each channel, providing flexibility for diverse monitoring needs.<\/li>\n
  • Accurate Flow Control<\/strong>: Electronic flow meters automatically compensate for voltage, resistance, and temperature changes to maintain stable flow.<\/li>\n
  • High-Performance Diaphragm Pump<\/strong>: Corrosion-resistant, low-noise, long-lasting, and equipped with overload protection.<\/li>\n
  • Temperature Control Protection<\/strong>: Automatic heating prevents solution freezing, suitable for low-temperature environments.<\/li>\n
  • Data Protection and Recovery<\/strong>: Automatically saves data during power failure and resumes sampling upon power restoration.<\/li>\n
  • Data Export and Printing<\/strong>: Supports USB export and Bluetooth printing for convenient field management.<\/li>\n
  • Particulate Filtration<\/strong>: High-efficiency dust filters protect the gas path system.<\/li>\n
  • LCD Display<\/strong>: Chinese dot-matrix display with automatic contrast adjustment for intuitive, clear interface.<\/li>\n
  • Cumulative Sample Volume Calculation<\/strong>: Automatically calculates and converts to standard volume, ensuring precise measurement.<\/li>\n<\/ul>\n
