Dual-Channel VOC Sampler

Product Overview
The Dual-Channel VOC Sampler uses adsorption tube sampling and other solid-phase adsorption methods to efficiently collect volatile organic compounds (VOCs) from ambient air, including benzene series compounds, aldehydes and ketones, halogenated hydrocarbons, etc. It can also be used in combination with a flue gas pretreatment system to measure VOCs in emissions from fixed pollution sources. This device is widely used in environmental protection, public health, labor safety, industrial monitoring, and scientific research fields for the detection of VOCs in ambient air and industrial waste gases.

Key Features

• Strong Negative Pressure Capacity: Equipped with an imported brushless diaphragm pump, capable of handling high-resistance loads with a maximum negative pressure capacity of over 20kPa, making it ideal for sampling gases such as benzene series compounds and TVOCs.
• Precision Digital Constant Flow Control: Built-in high-precision electronic flow meter, combined with an original flow control algorithm, ensures accurate control of even the smallest flow rates, achieving constant flow sampling.
• Long Battery Life: Features a high-performance lithium battery, allowing for over 20 hours of continuous operation on a full charge, suitable for long-duration field sampling.
• Automatic Heating Function: Automatically heats based on ambient temperature to prevent freezing of the sampling liquid, ensuring stable sampling conditions.
• Data Protection and Recovery: The system automatically protects data during power loss and resumes previous sampling conditions when power is restored, preventing data loss.
• Convenient Data Export and Printing: Supports USB data export and Bluetooth printing functions, making it easy to store and print sampling data on-site.

Applications

• Ambient Air Monitoring: Widely used for the determination of VOCs in ambient air, ensuring air quality meets environmental protection standards.
• Fixed Pollution Source Monitoring: Can be used to sample and detect VOCs in emissions from fixed pollution sources, assisting companies in controlling pollution source emissions.
• Industrial Waste Gas Monitoring: Suitable for detecting toxic and harmful gases in industries such as chemicals, pharmaceuticals, and petroleum, ensuring a safe production environment.
• Safety and Monitoring: Used for workplace air quality monitoring to prevent harmful gas leaks and protect employee health.
• Scientific Research and Education: Provides high-precision data support for environmental science research and educational experiments.
