Product Details
The KGD - WQ - 514 Motor Vehicle PN Rapid Detector is used to
measure the number concentration of fine particulate matter in
vehicle exhaust gas.
Product Introduction
The KGD - WQ - 514 Motor Vehicle PN Rapid Detector can be used to
measure the number concentration of fine particulate matter in
exhaust gas. The product adopts the DC principle (Diffusion
Charging Counting Method), which determines the number of particles
in the sampled gas by measuring the charge carried by the
particles. There is no need to filter and dilute the gas sample,
and it can directly measure the exhaust gas, ensuring the long -
term clean operation of the equipment and effectively reducing
maintenance costs. The product features high sensitivity, high
precision, fast response, and good stability. The high - definition
touch screen enhances the human - machine interaction experience.
Product Features
- Efficient measurement: No need for sample filtration and dilution,
with a fast measurement speed.
- High sensitivity: The diffusion charging counting method offers
high sensitivity to ultra - fine particles.
- Simple operation: Integrated calibration device, no need for
auxiliary equipment such as compressed air sources.
- Low maintenance: Through - type gas path, not easy to clog,
enabling long - term stable operation.
- Fast response: Using the diffusion charging counting method, the
response time is less than 10 seconds, enabling the PN - PTI
(Particulate Matter Measurement in Periodic Technical Inspection)
work to be carried out quickly and reliably.
- Economical and long - lasting: No soot blockage, not affected by
vibration interference.
- Quality assurance: Durable materials, sturdy structure, and low -
maintenance for greater durability.
