Product Details
KGD - WQ - 508 Partial - flow Particulate Matter Sampling System
Product Introduction
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.
Product Features
- 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.
