Model A Intelligent Dual-Channel Constant Flow Atmospheric Sampler

Product Introduction
The Model A Intelligent Dual-Channel Constant Flow Atmospheric Sampler is primarily used to collect gaseous and vapor-phase pollutants such as SO₂ and NOₓ from the air. It features significant improvements in portability, flow stability, and reduced labor intensity. The device utilizes a high-performance 32-bit processor, a dot matrix LCD screen, and advanced sensors, making it widely applicable in environmental protection, public health, labor protection, safety monitoring, military, research, and educational fields.

Product Features

• Dual-Channel Sampling Design: Offers flexible sampling capabilities, allowing for the simultaneous collection of two different gases or parallel samples. Each channel is independently controllable, meeting diverse monitoring needs.
• Precise Flow Control: Equipped with an electronic flow meter for automatic, precise flow control. The system compensates for flow fluctuations caused by voltage variations, resistance changes, or temperature shifts, ensuring stable sampling.
• High-Performance Diaphragm Pump: The sampler is fitted with a corrosion-resistant, long-lasting, low-noise imported diaphragm pump. It also features overload protection to prolong the service life of the device.
• Temperature Control Protection: The automatic heating function prevents sample solution from freezing, ensuring stable sampling even in low-temperature environments.
• Data Protection & Recovery: In the event of a power failure during sampling, data is protected, and sampling automatically resumes once power is restored, preventing data loss.
• Data Export & Printing: The device supports USB data export and Bluetooth printing, providing convenience for on-site operation and management.
• Particulate Filtration: A high-quality dust filter prevents particles from entering the system, protecting the sampling pump and gas circuit.
• Chinese LCD Display: The screen automatically adjusts contrast and is designed for use in cold, low-pressure environments. Its straightforward software interface enhances user experience.
• Cumulative Sampling Volume Calculation: The device automatically calculates the cumulative sampling volume, converting it to standard conditions based on temperature and pressure, ensuring accurate data.

Application Fields

• Environmental Monitoring: Extensively used for monitoring air pollution, assisting environmental agencies in detecting and managing air pollution.
• Indoor Air Quality Testing: Suitable for monitoring indoor air pollution and meeting the requirements of national standards for indoor environment control.
