Overview
Gasboard-9805 is a portable emissions measurement system (PEMS) for real-driving tests, combining PEMS-GAS (CO, CO2, THC, NO, NO2), PEMS-PN and PEMS-EFM exhaust flow modules with GPS and ambient sensors. Time-aligned data and total mass emission reports meet RDE requirements for on-road and off-road vehicles.
Key Features
- Self-developed gas analysis technologies including Infrared NDIR, UV-DOAS and so on.
- Modular design, flexible to use.
- Excellent performance meets high measurement standards.
- Easy operation, supports testing process guidance, data storage and report generation functions.
- More than 4 hours endurance of the built-in battery, no external battery needed supports complete real driving emission pollutant test.
- Great environmental adaptability, not affect by vehicle vibration, heavy pressure, ambient temperature and humidity change.
