Infrared Industries' HM5000 analyzer connects to the vehicle's exhaust. While driving, users will be able to see exactly how much HC, CO, CO2, O2 and NOx the vehicle is emitting. It also shows air/fuel ratio, grams/mile and Lambda, as well as a tachometer. The HM5000 can interface with a PC, PDA or data acquisition system. The HM5000 features a two-second response time for real-world applications.
