Aerosol Sensor Test System
New Products From This Supplier
The Aerosol Sensor Test System is designed for development, testing, and calibration of active and passive aerosol sensors, including PM and PN sensors. It combines features from filter media test systems with flexible sensor integration and broad flow ranges, enabling accurate evaluation of particle mass or number concentration. The system can be configured with two measurement sections to cover flow rates from 0.8 m³/h to 450 m³/h.
Application
(1) PM Sensor Calibration and Quality Assurance: For production-line calibration and quality control of PM sensors.
(2) PMx and PNx Sensor Development: Supports development and performance testing of fine particle sensors.
(3) Sensor Aging Studies: Investigation of long-term performance and aging behavior of sensors.
(4) Aerosol Technology Research: Supports fundamental research in aerosol measurement and instrumentation.
Standards
This system complies with and supports:
(1) GB/T 14295-2019 – Air filters.
(2) GB/T 13554-2020 – High-efficiency air filters.
(3) GB/T 6165-2021 – HEPA filter performance: efficiency and resistance.
(4) ISO 11057 – Filter media performance testing.
(5) EN 1822-4 – HEPA filter testing.
(6) ISO 29463-4 – High-efficiency air filter performance.
(7) ASTM D6830 – Evaluation standard for air filters.
