Product Details
KGD - MQ - 532 Infrared Gas Analyzer (Explosion - proof Type)
Product Introduction
The KGD - MQ - 532 Infrared Gas Analyzer (Explosion - proof Type)
adopts non - dispersive infrared (NDIR) gas analysis technology
with independent intellectual property rights and long - life
electrochemical sensing technology. It can simultaneously measure
the volume concentrations of gases such as CO, CO2, CH4, C3H8, O2,
and H2S online. The instrument is equipped with pre - treatment,
which can solve applications in harsh working conditions with water
and dust on - site. Its explosion - proof design can meet the gas
monitoring requirements in 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, and the measurement accuracy is
high. It has a self - diagnosis function and can check the sensor
status online.
- 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
pretreatment solution, featuring high automation and low
maintenance. Real - time online monitoring can be achieved without
manual attendance, greatly reducing the labor cost of enterprises.
- Simple Data Management: Data can be transmitted to the superior
centralized control system through multiple interfaces.
