Intelligent Four-Channel Constant Flow Atmospheric Sampler

Product Overview

The Intelligent Four-Channel Constant Flow Atmospheric Sampler is designed for the simultaneous collection of gaseous and vapor-phase pollutants, such as SO₂ and NOₓ, from ambient and indoor air. Compact and portable, the device offers high flow stability, significantly reducing labor intensity. It is suitable for both routine monitoring and emergency sampling of gaseous pollutants and aerosols, and is widely applied in environmental monitoring, public health, occupational safety, supervision, military, research, and education.

Technical Principles

The sampler features a four-channel independent system, allowing simultaneous collection of four different gases or parallel samples, with each channel independently controlled. An integrated electronic flow meter ensures constant-flow sampling with precise automatic flow control, while a high-performance imported diaphragm pump maintains stable operation. The device is equipped with anti-backflow dryers, backflow protection, and an automatic heating system to compensate for environmental temperature differences. Built-in pressure and temperature sensors monitor conditions in real-time, and cumulative sampling volume is automatically calculated and converted to standard conditions. In the event of power loss, the sampler automatically saves its status and resumes operation when power is restored.

Key Features

• Four-Channel Sampling Design: Collects up to four different gases or parallel samples simultaneously, each with independent control.
• Precise Flow Control: Electronic flow meter automatically regulates flow to ensure stable, constant-flow sampling.
• High-Performance Diaphragm Pump: Imported, ultra-low-noise pump with corrosion resistance and long service life for reliable long-term operation.
• Anti-Backflow Design: Efficient anti-backflow dryer prevents absorption liquid from flowing backward, enhancing sampling safety.
• Real-Time Monitoring & Automatic Compensation: Built-in pressure and temperature sensors automatically compensate flow deviations.
• Automatic Heating System: Compensates for ambient temperature variations to maintain stable sampling conditions.
• Chinese LCD Display: Auto-adjusting contrast, intuitive interface, suitable for low-temperature or cold environments.
• Data Calculation & Storage: Automatically computes cumulative sampling volume and converts it to standard conditions; data can be stored.
• Power-Off Memory & Recovery: Automatically saves sampling status during power loss or low voltage and resumes operation when power is restored.

Applications

• Environmental Monitoring: Routine and emergency monitoring of air pollutants such as SO₂ and NOₓ.
• Research & Education: Supports air pollution research and laboratory experiments in universities and research institutions.
• Occupational Safety & Supervision: Monitors industrial gas environments and hazardous chemicals for workplace safety.
• Public Health: Assesses indoor and outdoor air quality, including volatile organic compounds (VOCs) and other pollutants.
• Environmental Agencies: Provides accurate air pollutant data to support air quality regulation, source control, and policy decision-making.
