KGD-WQ-508 Partial-flow Particulate Matter Sampling System
The KGD-WQ-508 Partial-flow Particulate Matter Sampling System is an automated device that mixes clean air with a small amount of raw exhaust gas sampling airflow to form diluted exhaust gas, and collects particulate matter in the diluted exhaust gas through a filter paper. This device uses a high-frequency flow control strategy to quickly and accurately control the sampling flow rate, making it change proportionally and synchronously with the total flow rate of the engine's raw exhaust gas. Thus, it can quantitatively analyze the PM concentration of exhaust gas particulate matter under the transient operating conditions of the engine.
- Has two operating modes: proportional dilution and fixed-ratio dilution
- Has an automatic filter paper switching function
- Has a one-key automatic operation function for flow calibration and linearity check
- Has a constant-temperature control system for dilution air and diluted exhaust gas
