Instruments for On-Board Analysis
|
- Measures air fuel ratio (A/F), excess air ratio (λ), and oxygen concentration
- Wide measurement range—suitable for any engine type including lean-burn
- Rapid response time—approximately 80 ms
- Fast-response analysis of NOx from diesel or lean-burn engines using zirconia-ceramic sensor
- Direct insertion of sensor avoids measurement time delay
- Ideal for R&D, engine tuning, EGR adjustment, and on-road evaluation
- Very compact and light-weight (only 2.2 lb)
|
- Real-time, on-the-road measurement of CO, CO2, HC, NOx, A/F, vehicle position (GPS), exhaust flow rate, fuel consumption, vehicle speed, RPM, and more
- Easy to install—no operating gases required
- Independent power supply with rechargeable battery packs
- Laptop computer graphically displays and stores collected and calculated data
