KGD - MQ - 526 Online Gas Analysis System Product Introduction The KGD - MQ - 526 Online Gas Analysis System is designed for
working conditions with low dust in the sample gas. It consists of
three parts: the pretreatment unit, the control unit, and the gas
analysis unit. Using the non - dispersive infrared (NDIR) gas
analysis technology with independent intellectual property rights,
it can continuously and simultaneously measure the calorific values
of gas and biogas in real - time, as well as calculate the volume
concentrations and calorific values of multi - component gases such
as CO, CO2, CH4, H2, O2, and CnHm. This helps improve gas
utilization efficiency, save energy, reduce consumption, and ensure
safe production in industrial sites.
Product Features - Pretreatment Unit: Long service life and stable performance. It
uses a stainless - steel, electrically - heated temperature -
controlled dry sampling probe, which has a long service life and
high precision. The latest back - purging technology is used to
solve the probe clogging problem, ensuring the reliability of the
analysis system. A single - stage refrigerator is configured to
remove moisture from the sample gas, and two - stage filtration is
implemented to ensure the long - term online operation of the
instrument.
- Control Unit: Fully automated detection with simple operation. It
is controlled by a PLC program, which automatically completes
operations such as sampling, back - blowing, and drainage.
- Gas Analysis Unit: Simultaneously measures gas volume concentration
and calorific value.
- Low Maintenance and Operation Costs: Monitors the system operation
status in real - time without the need for manual attendance,
greatly reducing enterprise costs.
- Intelligent Data Management: Data can be transmitted to the
superior centralized control system through multiple interfaces,
providing real - time basis for remote monitoring and on - site
process adjustment.
