Product Overview
The Model B Dual-Channel Constant Temperature and Constant Flow Atmospheric Sampler is designed for collecting gaseous and vapor-phase pollutants such as SO₂ and NOₓ from the air. This equipment complies with the relevant standards such as the "Atmospheric Sampler Verification Procedure" (JJG 956-2013) and "Technical Requirements and Testing Methods for Ambient Air Samplers" (HJ/T 375-2007). It is known for its stable performance and ease of operation. The sampler uses solution absorption to collect harmful gases from environmental and indoor air, making it widely applicable for environmental protection, public health, labor protection, safety monitoring, military, research, and educational fields. It is suitable for both routine and emergency monitoring.
Main Features
- Dual-Channel Sampling Design: Supports the collection of two different gases or parallel samples. Each channel can be independently controlled, offering flexible sampling options.
- Precise Flow Control: Equipped with an electronic flow meter for automatic and precise flow control. The system compensates for flow deviations caused by voltage fluctuations, resistance, and temperature changes.
- High-Performance Diaphragm Pump: Uses an imported high-performance diaphragm pump that is corrosion-resistant, low-noise, long-lasting, and has overload protection to extend the service life of the equipment.
- Anti-Siphon Drying Device: Effectively prevents the absorption liquid from being siphoned back, avoiding operational errors and enhancing safety.
- Particulate Filtration Function: Built-in high-quality dust filter prevents particles from entering the gas path, protecting the sampling pump and the gas circuit system.
- Constant Temperature Control: Equipped with an automatic temperature control system that ensures stable temperature during the sampling process and rapidly reaches a constant temperature state.
- Chinese LCD Display: The display automatically adjusts contrast for low-temperature environments. It has a simple and intuitive interface, improving the user experience.
- Real-Time Monitoring and Data Calculation: Capable of real-time monitoring of atmospheric pressure and temperature, automatically compensating for flow deviations, while also calculating the cumulative sampling volume and converting it to standard conditions.
- Power Outage Protection: Equipped with power outage protection during sampling, and the sampler automatically resumes after power is restored, ensuring no data loss.
- Data Storage and Printing: Supports data storage and printing, making it convenient for future analysis and record-keeping.
Application Fields
- Environmental Monitoring: Used for routine and emergency monitoring of atmospheric pollutants such as SO₂ and NOₓ, helping environmental agencies assess air quality.
- Indoor Air Quality Testing: Suitable for monitoring harmful gases in indoor environments, meeting indoor air quality control standards.
- Scientific Research and Education: Widely used in research institutions and universities for studies on air pollution and for educational demonstrations.
- Labor and Safety Monitoring: Can be used to monitor gas concentrations in work environments, ensuring the health and safety of workers.
- Military and Security: Ideal for military and security sectors for air quality monitoring, ensuring environmental safety in operational areas.
