Product Details
KGD - MQ - 514 Combustion Efficiency Analyzer for Industrial Sites
Product Introduction
The KGD - MQ - 514 Combustion Efficiency Analyzer 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, and O₂, as well as the
flue gas temperature, and calculate the excess air coefficient,
providing a basis for adjusting the combustion conditions in
industrial sites.
Product Features
- Simultaneously measures flue gas components and temperature: It can
simultaneously measure the volume concentrations of gases such as
CO, CO₂, and O₂ in the flue gas, and automatically calculate and
display the flue gas temperature and the excess air coefficient.
- High measurement accuracy: It has a wide measurement range. The
sensor will not be damaged due to over - range, and it has a long
service life and high accuracy.
- Portable body design: Equipped with an integrated imported sampling
gun, it is easy to carry and can meet the needs of both on - site
industrial measurement and laboratory airbag sampling analysis.
- Intelligent power management: It is equipped with a soft - start
power switch to prevent the instrument from operating under low -
power conditions.
- Simple data management: It automatically stores measurement data,
has query and deletion functions, and can transmit data to the
superior centralized control system through multiple interfaces.
