Product Details
Explosion - proof Infrared Gas Analyzer KGD - MQ - 510 for
Industrial Site Safety
Product Introduction
The Explosion - proof Infrared Gas Analyzer KGD - MQ - 510 adopts
non - dispersive infrared (NDIR) gas analysis technology and long -
life electrochemical sensing technology with independent
intellectual property rights. It can simultaneously measure the
volume concentrations of gases such as CO, CO₂, CH₄, C₃H₈, O₂, and
H₂S on - line. The instrument is equipped with pre - treatment
components, which can solve applications in harsh working
conditions with moisture and dust on - site. Its explosion - proof
design can meet the gas monitoring needs of flammable and explosive
places in multiple fields, ensuring the safety of industrial sites.
Product Features
- Explosion - proof Design: The instrument adopts an explosion -
proof design. The flame - proof enclosure separates the internal
space of the equipment from the surrounding environment. It ensures
that when an explosion occurs, the enclosure can withstand the
explosion pressure without being damaged, and prevents the flame
from passing through the flame - proof gap to ignite the external
explosive environment.
- High Measurement Accuracy: There is no cross - interference among
multi - component measured gases, resulting in high measurement
accuracy. It has a self - diagnosis function, enabling on - line
inspection of sensor status.
- Stable Working Performance: The sensor adopts a dual - channel
design, which is highly stable. All parts in contact with the
sample gas are made of special heat - resistant and corrosion -
resistant materials such as stainless steel and
polytetrafluoroethylene.
- High Degree of Automation: It is equipped with a professional pre -
treatment solution, featuring high automation and low maintenance.
Real - time on - line monitoring can be achieved without manual on
- site operation, greatly reducing the labor cost of enterprises.
- Simple Data Management: Data can be transmitted to the superior
centralized control system through multiple interfaces.
