OBS-2000
Overview
In addition to concentration measurement of CO, CO2, THC and NOx emitted from moving
vehicles, the OBS-2000 series also calculates mass emissions for these gases and fuel consumption. OBS features include an exhaust flow meter, a GPS receiver for global positioning data and other sensors to monitor engine parameters and atmospheric conditions in real time.
Features
ADVANTAGES
- The OBS-2000 series is a system that analyzes vehicle emission in a real-world situation
- CO and CO2 concentration in vehicle emissions is measured by a NDIR analyzer without water extraction
- THC concentration is measured by a FID analyzer
- NOx concentration is measured by a CLD analyzer
- OBS-2000 series also calculates mass emissions for these gases and fuel consumption
- Compact, self-contained analyzer unit, enabling it to fit in a small space
- Easy installation and operation
- Suitable for all types of vehicles, from cars to trucks, and a variety of fuel types
THE APPLICATION
HORIBA engineers created the OBS-2000 series in response to new requirements for exhaust measurement from vehicles being driven on the road. The OBS-2000 series allows you to measure actual exhaust emission under real-world conditions and investigate the relationship between emissions and other parameters such as type of vehicle, fuels, driver behavior, traffic, road conditions, and weather.
Efficient data collection supports energy and environmental decision making.
With this flexibility, the OBS-2000 can significantly contribute to pollution reduction studies and improved fuel economy. Vehicle emission measurement is no longer limited to the laboratory. Placed on-board a vehicle the OBS-2000 Series emissions capabilities permit a broad range of practical applications.
