Category:

The MVSS-90 Medium-Volume Sequential Sampler is an advanced air sampling system, engineered with cutting-edge  technology. It provides a 100 L/min sampling flow rate, designed for the precise collection of airborne particulate matter such as PM10, PM2.5, and other fine particles of varying sizes. The system can automatically replace up to 18 filter membranes during the sampling process, ensuring uninterrupted operation for extended periods. With its built-in low-temperature storage capability, it effectively prevents the loss of volatile organic compounds (VOCs), making it ideal for environmental monitoring and research. This sampler also supports a wide range of analyses, including air quality concentration, inorganic ions, elements, organic carbon, organic substances, and particulate matter dispersion.

Key Features of the MVSS-90 Sequential Sampler

  • Durable Mechanical Design: The filter membrane conversion system features a robust, mechanical design that ensures smooth operation and prevents filter jams.

  • Efficient Filter Membrane Storage: The filter membrane storage tray holds up to 18 filter holders and securely fastens them using a steel plate spring, preventing dust contamination during prolonged sampling sessions.

  • Intelligent Filter Identification System: Optional RFID and smart filter identification system enable automatic recognition and data transmission of each filter’s sampling and weighing details. With integration into a cloud platform, remote task management (setting, starting, and stopping) and real-time monitoring are possible.

  • Remote Data Monitoring: Optional GPRS wireless transmission module enables the remote monitoring of sampling data, enhancing operational flexibility and control.

  • Meteorological Data Integration: Optional wind direction and wind speed sensors allow the system to provide comprehensive data analysis, combining meteorological parameters with particulate matter mass concentration.

  • Real-Time Parameter Display: Sampling parameters such as temperature, humidity, membrane pressure, and atmospheric pressure are displayed in real-time through an easy-to-read graphical interface, ensuring efficient monitoring.

  • Peltier Cooling for Filter Membrane Preservation: The optional Peltier cooling system keeps the storage temperature of filter membranes below 20°C, effectively preserving volatile substances and ensuring sample integrity.
